The world would be a lot safer place if upon seeing the light turn yellow, we all asked ourselves “Can I stop without throwing the dog through the windshield?” instead of “Can I make it through on a little bit of yellow?”
Europe, in the next few years, is going to require car instrumentation panels to have more actual physical buttons and knobs instead of touchscreen ones if the car is to receive the highest safety rating. You generally don’t have to take your eyes off the road to turn a knob.
I heard a song the other day where part of the lyric was “driving down the PCH at 120mph”. My own contribution to making cars safer would be to change the speedometer so that any speed above 90 or so just said “too fast!”
Here, for example, is the speedometer in my Hyundai Santa Fe Sport:

Why in the world do I need a speedometer that goes up to 160????
I have my doubts that even on a downhill slope the car could actually go that fast. And I know for sure that I would not want to be in it if it did.
It would make much more sense to have the speedometer going from 0 to 90.
