When I do road trips I'm staying at a variety of motels, mostly the better ones. Aside from not leaving valuables in the car, parking under lights and locking what are some simple methods to discourage theft? The chargers seem to be near the top of the list for stolen cars nowadays. I'm thinking of steering wheel locks, mechanical devices and not so much the complicated electronic devices. It would be nice though to have my phone alert to any movement of the car, immediately. Not sure what that entails. Thanks for ideas.
