I'm pretty sure where I live they already don't use chalk, but instead use cars/gocarts with license plate scanners, driven by parking enforcement officers, that drive up and down the streets, recording what cars were where when. The system will flag em to stop and ticket where required.

I think this is quite common now in the US?

Googling, I'm not sure if it's not quite common yet (yet!), or there just hasn't been a lot of attention to it?
