Doing that for thousands of cars, at boarding and then at unboarding, looks like a huge logistics chalenge (even just thinking about changing every ship’s floor to allow for strapping) that has a pretty high cost that might exceed losing part of the cargo once in a blue moon. Shipping cars in containers sized structures could be a more realistic approach perhaps.
