The problem is it wouldn't stop many thefts.
These scooter-riding scumbags either bike-jack you and your key, or they just steal it when parked, and push it along the road with their scooters. They don't really care if the engine won't run.
This is why the proximity thing would work or phone app with tracker. They ride off, you kill it and then find them/the bike. They won't as happily push it down the road if its on a high street in broad daylight so would help you about town I'd have thought
