Just putting it out there, but how many people would be prepared to have their cars acceleration and top speed locked down if it gave them a significant discount on their vehicle insurance?
I am sure there are many people who didn’t buy their Tesla for its performance and would quite happily trade some of that potential for a significant cut in insurance premium.

I don't see why not - it's a pretty standard thing on motorbikes - power levels are only available on passing certain licenses or age of the driver/rider. Carrying passengers only with full licenses etc.
I still don't understand why this isn't a thing on cars...
