I feel not as many robbers will want to steal the large battery from a electric car because there is a chance of being electrocuted and an electrical fire if a robber don't know how to safely remove a large battery. Removing the electric motors, and other electric parts may also be dangerous for untrained robbers. Plus, there are not many buyers who want to buy used electric car parts like used gas car parts like a gas tank, engine, transmission, and exhaust system. A used electric motor and battery for a Tesla electric car most likely does not work on a Nissan Leaf electric car without heavily modifying the car. Finding a car repair which can install used electric car parts can be hard, and owner's electric car dealer may refuse to install used electric car parts which you bought in, and they may report you to the police if they think you bought a stolen electric car parts.
