Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Absolutely.
1) Adjust mirrors and use that as first step.
2) If you have BSM, check.
3) Quickly turn your head and double (triple) check.
I remember in driver's ed class one of the students turned his head and just started looking backwards for what seemed like 5 seconds, while our driver's ed teacher calmly grabbed the wheel and brought us back from certain death.
He then explained the concept of a glance versus a look.
My Driver's Ed was so long ago that we had a '63 or '64 Ford. The front seats had seat belts, but the back seats did not. When not driving, the other students were in the back. One young lady who never quite caught on hit the brakes so hard the back seat passengers hit the back of the front seat. My knee hit a metal bracket on the seat back. I could hardly walk for a couple of days. Nothing the instructor could do. He kept the young lady out of accidents, but she often hit the brake like that and I got used to protecting my knee from that metal piece.
Oh, and we drove both manual and automatic cars! How cool is that?
