A stranger laying a hand on a phone is, based on experience, likely a stranger trying to steal it. It's totally rational there to be jumpy. Someone touching your bike is a awfully close to touching you. I think it's rational to be a bit suspicious when a stranger gets that close to you, no matter what they are doing, but especially if they are touchy feely. People touching my car will quite obviously do no damage to it or me. If I'm in the car, I may lock the doors/roll up the windows, if they aren't already. If you want to move the goalposts now and say a stranger isn't merely touching your car, but keying it, that's a different situation, and unrelated to the discussion. I don't know exactly what a rational response is to irrational behaviour. :)
