I've seen peak speed cameras for years going to Switzerland a lot to see my (awesome) in-laws. I would love to see peak speed camera here, with fees tied to income capabilities.
I once got a questionnaire for going 90 in a 30 near the border in Geneva. I didn't really the drop in speed was so severe, and I was focused on trying to figure out where to go. My mistake, bill was only 200 CHF, plus 3 month ban, since I didn't make much money at that point. I appreciated the system though, it made a lot of sense, and the driving culture is just so much better than here, because of the enforcement there.
