That'd be rad! To turn on a car with Bitcoin, you'd need:

1. A smart contract tied to the car's ignition system.

2. The car's system would have to be connected to the internet.

3. When you send Bitcoin and it confirms, the contract triggers and vroom – engine starts!

It's all about IoT (Internet of Things) tech mixed with crypto magic. Cool idea for sure! #BitcoinDriven 🚗💨
