Right, stop once for a traffic jam, car loses sync with keyfob, and you'll become a stationary target on a highway.

Better swap out those batteries in your keyfob real quick before that 18-wheeler smashes into your car with kids in the backseat!

But hey, at least your car won't be stolen!

> Problem solved.

I guess this proves my point I was trying to make in my original post. Every xx months a sensation article like this comes out, and suddenly everyone, even on HN, becomes an expert that will 'just' solve the issue with a naive solution.

Car manufacturers, hire smart engineers. If the solution was simple, they would have fixed it already. Cars are always a trade-off between safety, security, reliability, affordability and practicality.

Great that your solution makes car theft resistant, but if also kills people, it's not such a great sell...
