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

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.
