On my street they installed one of those 'current speed' radar displays to let people know they are speeding.

I've never thought they worked really, but this is a new one. It has very prominent red and blue flashing lights that trigger if you are 5+ over. I've seen countless people slow down immediately, it's that jarring/terrifying

the side effect is bikers like me will pedal as hard as possible in hopes we can get that light to flash

I assume you are talking about cyclists. So in this case i guess it's not a biggie as they are moving the mass of no more than 20kg compared to 2000kg when driving a car. (from safety perspective)

That's because a lot of those people think it's a "speeding ticket" camera flashing at them.
