I would recommend one with at least 2 cameras. One facing forward and another in the back window. Nextbase 422GW is the best of the best. Add Nextbase Rear Window Camera for your rear facing camera and you'll be set up for anything. If you just want one camera, I would go with Vantrue N2 This is the one that I bought when I was thinking of doing a little UBER on the side, but never did. After, I wished I had sprung for one with a 2nd camera for the rear window. But it does have the advantage of recording what goes on inside your car... which is good if you ever want to do any UBERing or LYFTing. =)
