As I was walking out to my car yesterday evening, I started thinking about the cars parked in the garage. If Transformers mimic other vehicles with such accuracy, does that include weight as well? Now, as a precursor, it's all science fiction and cartoons, so there's really not much plausibility to any of this. Still... * In the G1 cartoons, the Autobots seemed to have no problems with weight, whether in robot or in vehicle mode. If they were walking on concrete or driving on asphalt, they, apparently, didn't have enough weight to cause cracks or anything in the concrete. Since that's G1, that's pretty forgivable. * In the movies, it looks like the robots are capable of staying pretty dextrous, both on their feet and in vehicle form. However...here's what I was thinking about. Let's say you stand a car on its head. The distribution of weight for the car has now shifted from equally being distributed through four tires equipped with shock absorbers TO one bumper (or however you get the thing to stand up.) Because all of this downward gravity force is now centered in one location, both the car AND the ground have to give a little to compensate. Where concrete could easily facilitate a car on four wheels, I'd assume it would crunch a little under the weight of a car standing on end. Similar argument with a human being - if a person lies on a mattress, their weight is evenly distributed across the mattress. If a person stands on a mattress, though, there's a much deeper depression where the person's feet are. SO...if Transformers - in the movie universe, in G1, whatever - transform from vehicle to robot mode and walk around, wouldn't their switched form cause larger depressions in the ground? Wouldn't they crack concrete and damage asphalt if they were standing/walking around in robot mode?
