Hey Jeno, Like you mentioned in your signature about your left wheel you can calculate the distance of rear end too…
In my opinion reverse parking sensors are really helpful I got a 2 inches cut in left side rear bumper guess whats its devidor For which I need to replace the whole bumper + painting big hole for me
In that budget I could easily get sensors fixed but now its too late.
Go for Camera its more functional.
