If you want battery life, you probably should stay right away from Gopro. They think 90 minutes is a long time. 2.5 to 3 hours is their outer limit for some models in the most battery conservative settings.

One thing that EVERYONE is always saying is "I want to be sure to be able to read license plate numbers" - I have so far found NO camera that can reliably do that in all situations. In low light, I don't think it's even possible Sony action cams, with the backlit sensor, in 60 fps mode, have the best shot probably, but if a car is passing you at 30 MPH faster than you're going, you just don't have the bitrate to see the numbers.

It's possible that if you get a camera that can do 4K at a really high bitrate (like 60 Mbps or something) then in daylight you could always read the plates, but even then I think you'd probably fail in low light. And at that point you're up into Black Magic cams, which start at $1000 just for the body, then you start shopping for lenses.
