I have to say, having taken an Uber in many states and countries, in MA, having a plate on the front and back is much easier to find the car! I hate in one plate states, a white RAV4... Oh goodie there are three in a row! Lol.

Inspections... The places without inspections you see more cars missing a brake light than the ones with all 3 lights. I don't love a nanny state but I do like knowing when the person in front of me is stopping so I can too.
