The issue of driving a manual car was pointed out to me and I had to go improve my driving technique

My Family's Car Life

stepping on too many manholes

My husband said this to me the other day as I was driving my Boxster.

Why do you have to step on all those manholes and run (-_-)?

And. ."Oh, there was a manhole? I didn't see any.I answer, "No.

I was stepping on them all over the place. I think it is better to run without stepping on manholes as much as possible, especially when they are uneven.

They said.

After that, I tried to run consciously not to step on manholes... but there were so many of these manholes. "It must be every 10 meters.The "Tire Treader" is so numerous that it is placed just where a tire would step on it.

Also, I had to shift gears, look at manholes, and check my surroundings while driving... there was just so much to do that I didn't think I'd be able to do it.

Oh no, I can't even try to avoid it.

if it were the case that

You don't have to force yourself to avoid everything...but you need to look further ahead when you drive. Driving with your eyes fixed on the nearest manhole leads to unreasonable handling.

And.

I want to run without stepping on manholes.

So I did some research on the relationship between manholes and car tires.

Tires are rubber.On the steel, my grip was almost nonexistent.Slip.
There are about 15 million manhole covers installed in Japan for sewerage use alone.Approximately 3 million of them have exceeded the standard adoption period (30 years) set by the government.Aging is a concern.
During rainy weather, manhole covers can become slippery, which can cause automobile tires to slip and cause accidents. Motorcycle riders, in particular, should be aware of this.Even in clear weather, manhole covers are "basically to be avoided."The first is.
The oil pan on the bottom of the car came in contact with the corner of the manhole and broke, causing an oil leak.
Accidents such as flat tires on cars due to protruding manholes, etc. have occurred.

There was a If there are no cars around, but if a car slips when there are oncoming or following carsIt could lead to a major accident involving others.In this sense, there is still no better way to be aware of running without stepping on manholes.

Also fresh in our memories is the Azerbaijan GP, the fourth round of this year's F1 season, which was red-flagged when a car stepped on a manhole cover, causing the manhole cover to come off and hit the floor below, sending debris flying and forcing the race to be red-flagged.

The FIA has been working with the "The manhole cover came loose due to a broken fastener.I guess manhole covers are not to be underestimated.

Also, one article states.

On rainy days, the difference in grip between manhole covers and asphalt pavement is significant. There is also the difference in the coefficient of friction, and the difference that rainwater can soak into the asphalt to some extent, while water can accumulate on the steel plate. Therefore, there is no need to step on manhole covers with tires, and it is safer to avoid them if you can.
Source.I sometimes see cars avoiding manhole covers, should I not step on them?

It was written.

I see... butIt's pretty hard to avoid manholes.I guess so. It would be pointless to drive carelessly in front of the manholes or out of the oncoming lane if one is too preoccupied with the manholes, but as we enter the autumn and winter season, I would like to drive without stepping on them as much as possible.

    Reading the article reminded me that I used to use the "neutral strategy" (lol) when I first started MT.
    But I don't do it now because as your husband said, neutral is dangerous when you need to start and stop the car at a moment's notice. When the road is clear and there are no cars in front or behind me, I sometimes put the car in neutral to mimic PDK coasting, but I wonder if it helps fuel economy.

    I have participated in warm ups in PTE, formerly known as PDE. I remember it was the lowest class, but it was still exciting enough, and the Gs generated by full acceleration and sudden stops made for a great show. I hope you will be able to participate in full physical condition.

      Mr. Ishi.

      I'm getting used to driving a manual transmission itself, but I'd say I'm completely intimidated by the Porsche.
      It's the same MT car, and the Boxster is usually easier to drive, but I feel like I'm completely in the mood (laughs).

      But the neutral strategy is still no good...!

      I see you attended warm up!
      Precision also seems to be quite similar in what it does.

      I'll do my best on the day!

    Nice to meet you.
    Manholes are slippery on rainy days, so I avoid running through them too.
    The joints of highway piers, which are steel sections, are also slippery and sometimes make me cringe.
    Be especially careful at joints where there are corners.

      >The joints of highway piers, which are steel sections, are also slippery and sometimes make me cringe.

      As you say, it's scary at the highway joints...
      I too have had my share of near-misses.
      I'll be careful about manholes and joints, especially in the rain!

    I see that running with the car in N is called the neutral strategy. I had never heard of it before.
    I use it in MT, but only when I can confirm from the road conditions, etc., that neither my car nor the other car has the option of changing lanes.
    In my normal driving, what do the people driving around me want to do next? They are leaning to the left, so do they want to make a left turn? I try to observe and make predictions. I also like to observe (laughs).
    I also believe that you can't afford it, you have to make it (laughs).

    I'm looking forward to seeing Mina brilliantly maneuvering and dashing around in her Boxster! (^^)

      Mr. Esta.

      >I see that running with the car in N is called the neutral strategy. I had never heard of it before.
      No, it was just a couple of people talking on their own (laughs).
      As Esta said, it is really important to check the situation and operate properly.

      I'm getting used to driving a manual transmission vehicle itself.
      When it comes to Porsche, I am completely swallowed up by its presence... (laughs)
      I'll make sure I get used to it!

      I look forward to seeing you again in Ashi Ari!

    Hello. Is it a neutral strategy?
    In the old days, we were told to always put the car in gear while driving, but now that we live in an age where PDKs and the like will disengage the clutch and coast on their own, I am trying various things with manuals as well. You may say that this is an evil way.

    In chess and other games, professionals use AI as a reference, but I think it is imaginative to use PDK as a reference. I have very little experience with PDK, so I am guessing, but I think that PDK instantly selects the best gear for the next operation even if it is coasting. Is it the neutral strategy of manual? I think it would be good if we could always be aware of the vehicle speed and put the car in the most appropriate gear when necessary. If we talk only about the movement of the shift lever, putting the car in neutral is almost half the operation. If I want to coast from 50 km/h while decelerating, and if I need a little acceleration in the city, in the case of my 991.2, I can put it in 4th gear for 40 km/h and 3rd gear for 30 km/h. If I want quick acceleration even at 40 km/h, I can put it in 2nd gear while blipping a little. If you want quick acceleration even at 40 km/h, you can put the car in 2nd gear while blipping a little. However, since there seems to be no difference in fuel consumption between accelerating off the gas pedal and coasting in 6th or 7th gear, I am beginning to think that coasting is not necessary. Since the only thing they are aware of is the vehicle speed and the gear that matches it, coasting or not is not really relevant.

      Thank you for everything!

      >I think it is possible to use PDK as a reference in terms of image.

      Well...you are certainly right about that.
      The PDK system is indeed able to instantly select and smoothly change gears according to the situation.
      It would be nice if we could be aware of that same kind of movement, wouldn't it?

      There's still a part of me that's pretty intimidated by the atmosphere just because it's a "Porsche with a manual transmission."
      From now on, I hope to drive many MT Porsche cars and get used to them.

    I was hoping that I might be able to say hello to Mina-san since you are attending PTE, but of course you are in Kansai....

    I will be attending Precision in Fuji in October!

    I'm really looking forward to seeing the training programs of European manufacturers, as the curriculum is often tailored to the characteristics of that manufacturer's cars. (From the menu, I'm assuming it's mostly fixed to 2nd gear.)

    I looked at the PTE web site to see if there was any difference between the racing course at Fuji and the airport site in Kansai, but it seems that instead of the main course experience at Fuji, there is a full-throttle challenge and a test ride of the latest models in Kansai.

    (Depending on the pace of the lead driver, the experience on Fuji's main course, which is very wide, is quite boring, if not yawn-inducing, so the Kansai program looks better.

    I'm really looking forward to the up-date on your PTE participation now!

    • Mina.Mina.

      Mr. Tap.

      >I will be attending Precision in Fuji in October!
      Oh yes!
      Actually, my husband is taking the Master at Fuji in October, and I was thinking of following him as a family.
      But the dates are not the same as Precision... too bad>.Instead of the main course trial run at Fuji, I see that there will be a full-throttle challenge and a test ride of the latest models in Kansai.
      Certainly, being led around the Fuji course makes you want to drive faster if you are used to it ^^;.
      I've never driven a car at an airport before (of course w/o a car), so I'm very excited and nervous about it.

      I will blog about it again!
