I had posted a comment about making changes to make the car safer (reduce chance of accident). But further thought:
1) Install the wide angle side mirrors.
2) Install the high mounted third brake light
3) Use LEDs for all the brake lights.
4) Get the front side running flashing with turn signal lights.
5) Get the rear side running flashing with turn signal lights
6) Use LEDs on your flashing side running lights.
I have done everything except getting the rear side running lights flashing. Never thought about getting the rears done because most cars don't do it, but it may buy you that warning if your passing a car in your blind spot.
