I have been always wanting to ask this question but hasent anyone made a car not be able to be picked up on a speed radar stealth aircraft exist and I’d assume the radar the cops use is much less advanced then military radar and would be easier to fool is it a resources thing it would be to expensive or is it impossible with all the crazy shit online I’m surprised someone didn’t try it yet

Can I buy a 49cc moped without a title do these bikes even have titles and do I need to get it registered and have a licence to ride it
