My guess set up a prepaid amount in a trust with a timed release of funds. And a contract set up with a lawyer. The overriding issue you are liable for the car regardless. If it gets damaged etc, Tesla will say it’s on you. If they find out you sublet the car all bets off. Same
Goes for insurance I would imagine. Personally speaking, I would just take hit of breaking the lease and use it as a life lesson. Less risk
