I thought it was obvious. Charging (scoping just to US) has some difficulties. First, you need to know how charging works (110V vs 240V vs DC fast charging) and also understand what kind of charging the car you are stealing supports: https://www.power-sonic.com/ev-charging-connector-types. Also understand the various apps that are needed for different cars and how they work. The thief most likely may not have charging at home or at work (if they have a place of work, I'd assume they are not working at FAANGs, which have 2 - 3 EV chargers at each location). Then, when they are chased by cops, etc, they will eventually run out of charge. They can't do a quick pitstop. When they are charging, lets say at a Tesla station, the car may be electronically identified. But, most importantly, the media instills a fear of electricity (you can't find electricity anywhere except these things called EV charging stations and there are very few charging stations) and electric cars. Everyone is worried about range (range anxiety).
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.
