Simple,. Contact the police and report it as stolen.

Unless it was a new car, it's doutbul that a product liability case exists. Best case is against owner and driver..Hire a personal injury attorney...

Sorry but unless you were made sick and received medical care, there is no case. Seek a refund.

Report incident to the police if it happens again.

If not reimbursed, you can reference mileage on your taxes next year.

You don't need to pay a lawyer. Either go thru your own Carrier and they'll sue for you or sue the d owner/driver in small claims court.

You could sue them for conversion, civil theft, fraud, breach of contract, etc for not returning the vehicle.

You'll need to hire a criminal defense attorney ASAP!

Sorry to hear that but it's not a case. Unless you ate it, got sick AND received medical care, there are NO damages. What COULD have happened means...

Nothing to fight. You could possibly recover for your medical bills if you could prove that the establishent caused it.
