This has probably come up before but do you think it is taught or necessary to look over your shoulder to check blindspot when changing lanes on the motorway?
I just need to add an edit. I’m specifically referring to looking over your shoulder on a motorway. Checking mirrors and blindspot is not under question
I was taught to do that, and I hope everyone does it, even if they think they’re the only car on the road. I’m a very safe but confident and decisive driver, and the number of times I’ve looked over my shoulder and been surprised by what I found is high enough that I will continue to always do it, even if it feels silly. It’s just not worth the risk.
