While the basic premise is somewhat plausible, the execution is not. First of all, “hotwiring” went out of fashion fifty years ago, when GM came up with the locking steering column, which locked the steering wheel and the gear selector mechanism. While motor vehicles are still being stolen, it requires a bit more sophistication than simply twisting two wires together.
The modern variation on auto theft, which involves sophisticated electronics, is a reality. This makes one wonder what they were thinking when they came up with the idea of RFID technology, so that one need not reach into one’s pocket to use a car key to enter and start a vehicle. What could possibly go wrong???
