Right now some lawyer is trying desperately to figure out who he can sue. Maybe he’ll sue the car manufacturer because they didn’t make the gas pedal immune to interference by dog.
Easy. The driver. Pretty clear case. Driving a car with an un-restrained animal (especially in your lap)is dumb. It can cause an accident (like this) or, in the event of an accident the animal you care about can get hurt or hurt YOU as it flies around the cabin. I drive with a St. Bernard and 103lb lab. Both are buckled in in the back seat for my safety and theirs.
