Only if it happens to be someone I know: the times have changed enough that I'm not likely to offer a stranger a ride anymore. A stranded motorist won't get me out of my vehicle, or the windows rolled down, but I will offer to call for help via my cell.
One of my colleagues was knifed by a 'customer', and the new vehicle out for a test drive, stolen.... um, even when it's supposedly 'safe', it isn't!
