A case where a problem with driving a manual car was pointed out and it was decided to polish the driving technique
Too much manhole
The other day, when I was running Boxster with my driving, my husband told me this.
Why do you run on all such manholes (-_-)?
When. "Well, was there a manhole? I didn't see it at allIf you answer
I was walking around the street. Especially in the case of uneven manholes, it is better to run as little as possible.
It was said.
After that, I tried not to step on the manhole, but I ran ... I have a lot of manholes. "Maybe every 10 metersIt is installed in a place where tires can be stepped on.
Also, while shifting and running, looking at the manhole and checking the surroundings ...
Oh, it's impossible to avoid it (゚ д ﾟ)!
It ’s okay to avoid it all, but… It ’s not easy to handle because you ’re driving around the nearby manhole.
I want to run without stepping on the manhole
So, I examined the relationship between manholes and car tires.
-Since the tire is rubber,The grip is almost ineffective on iron,slide.
・ There are about 15 million manhole covers installed in Japan, only for sewerage.About 3 million units have exceeded the standard adoption years (30 years) set by the country,There are concerns about aging.
・ The lid of the manhole becomes slippery when it rains, so the car tire may slip and cause an accident. Especially for bike riders,Even in fine weather, the manhole cover is basically “avoidable”.
・ After passing through a slightly raised manhole while decelerating, the oil pan on the bottom of the car contacted and damaged the corner of the manhole, causing oil leakage.
・ Accidents such as car punctures due to protrusions such as manholes have occurred.
It was. If there is no car around, if the car slips when there is an oncoming car or a following car,It may also lead to a major accident involving the surroundings.In that sense, there has never been a consciousness of running without manholes.
Also new in memory is this year's F1 Round 4 Azerbaijan GP. There was an accident in which the running machine stepped on the manhole cover and the manhole cover was released and hit the bottom of the floor, debris scattered, and the race was interrupted by the red flag.
FIAManhole cover loosened due to broken fastener"I don't want to speak the manhole cover."
In one article,
On rainy days, the grip difference between the manhole cover and the asphalt pavement increases. There is also a difference in the coefficient of friction, and asphalt is slightly infiltrated with rainwater, but there is also a difference that water accumulates on the iron plate. Therefore, it is not necessary to dare to step on the manhole cover with tires.

It was written.
I see ... butIt's hard to run around manholesWell. It is meaningless if you drive too carelessly or run out of the opposite lane because you are distracted by the manhole, but in the coming autumn and winter, I want to run as much as possible.
