You're assuming so much that is wrong. Thieves don't know how to use technology?
They can't use a charger? (I imagine they'd wire one to an also stolen generator)
Then you assume they're gonna be in a car chase? That's not how most stolen vehicles end up.
Afaik most stolen vehicles either get quickly parted out at a chop shop, or are sent across a border (driven across borders or container shipped to another country), or used for other crimes, or they're joy rided around then abandoned. Basically all things you could easily do on a partial charge with a modern car mechanics skills.
