Depends
Explain the depends part. What would stop you from pulling over if it was obvious something was broken?
No, I dont trust people. I would love to stop and help someone, but the chance of something going wrong and them suing me, or someone shooting me in the face isnt worth it. It's sad, but its the world we live in now.
good point and +1 on the hot chickim sort of one of those a-holes that believe if you cant fix a simple flat or what not, you shouldnt be driving. Though maybe if a hot chick caught my intrest.
