Here’s a tip for some of you drivers out there. It stems from my experiences as a motorcyclist and now as a driver, although now I’m not travelling quite as fast. The bike was an 1100cc machine and my car is a diesel estate!
I noticed in the past that whenever I was coming up behind a car on a motorway and that car was indicating to pull out into my lane that the driver would (I assume) check the rear view mirror or door mirror. Now, if the driver looks once and gets a snapshot of the road they would see me in the outside lane. What would be interesting is that the driver would have no idea of how fast I was travelling unless he/she spent a long time staring in the mirror. To get an impression of speed the driver would have to look again in the mirror to see how my position relative to him/her had changed in the time that had passed.
I believe it is for this reason I had cars pull out in front of me causing me to brake many times. It is quite simple that to judge a speed you need two reference times to see position change. Hence drivers need to look in their mirrors twice before pulling out in front of traffic in the next lane. Most drivers are ignorant of this fact of physics given that cars still pull out in front of me and I’m now in a car.
Perhaps drivers don’t care about other road users and I’m in the minority. Gosh, I think I’m better than most.
