Why you should always assume the driver has not seen you

And second I think Oliver is right; you shouldn't assume a driver hasn't seen you because you should not be working on assumptions. His point about eye contact is entirely valid; make it and you know you have been seen. gathered.

Assuming a driver will not stop has saved my ass so many times, and to think otherwise is ridiculous.
Trust he will stop ? or trust the driver to indicate and assume he drives completely error free ? No, you don't do that, it's something you just don't do, if you want to survive that is.
Preparing yourself on the "assumption" a car will pull out is pretty standard stuff, and like i said, it's saved me many many times.

Eye contact is optional
