Indeed, I've come across 3 or 4 in the last few months. First time I saw those chargers, I was like 'wait a minute....what are those things on the roof' then it hit me.
Thankfully I wasn't street racing Toretto at the time.
Yup it's 100% legal, as long as there are no lights and they don't claim to be police then they're in the clear.
Thank you blokes.
I think I said that with tongue in cheek.
Many years ago in the UK idiots where going around with yellow jackets with the word "POLITE" Not sure what happened to them.
