After a few very close calls over the years I drive with as much awareness behind me as ahead of me. I always leave wiggle room ahead of me when stopped in traffic and try to leave a emergency exit for a quick escape, I monitor the rear mirrors and tap the brake light in addition to having a brake modulator active during stops. I don't think a big black motorcycle is that noticeable so I like to take any precaution I can from becoming road toast.
