As a driver, I would rather have larger crumple zones or places to put curtain airbags and such than space to be able to fit a full size dog in the back. Regulations aren't always bad or a burden on the industry (or for that matter on the dog owners). Having an EV 80's chassis would be a great idea for a hobby build or something to take out for a Sunday drive to the country. But I would'd drive that death trap daily.
