Would this include a total revamp of everything in the cars?

Teslas product are inherently consumer hostile.

They are bad build quality,. The user interface is made to cut costs not good UX. You need a subscription for things already in the car. Autopilot shuts off just before accidents to not make Tesla liable for the incident.

The list just goes on.

Everything about that company screams “fuck you” at the people buying their product.

If you’re worried about your cat running away you shouldn’t let it roam free.
