I use a mirror and one technique I use when approaching a line of stopped vehicles is to 'bring in' the vehicle coming to a stop behind me. By that I mean that instead of going full bore and slowing fast to a stop I gradually slow and let the vehicle behind catch me and we both roll in a bit slower to the stop. This allows me to ID if driver notices me earlier while I still have time and space for evasive action (never needed so far.)
This same technique applies to approaching traffic stopped on freeway when driving a motor vehicle as well.
