Not so much road rage here but drivers are taking more chances and sitting too close. My bikes have very bright red LED at the rear and it can make your eyes uncomfortable so it help me out. Get some 9watt eagle eye lamps.
I use cruise control on all speed limits now including the 20 mph limits and if cars drive too close, its their insurance that pays for the rear ending.
Last week was unusual when a car overtook me on the bike when i was doing 20 mph in a narrow country lane. Very close to my right elbow.
