Tape drives are one thing that comes to mind.

In a lot of European countries, rest stop signs (along the highways) announce what amenities are available at the rest stop. Those signs include symbols for things like toilets, restaurants, gas stations as well as charging stations. Here's a German example. Pretty solid solution in my opinion.

This just in: shitty drivers don't know the size of their vehicle. More on this at 6 (apparently).
