1) Yes, NEWSFLASH, technology has improved a lot in 50 years. Of course, not all light cars are more dangerous than heavier cars. However, if you take otherwise identical cars with the same level of technology, the heavier one is going to offer more protection in a collision (and/or is able to include more safety features within its weight limit).
It all depends on HOW you improve gas mileage. Faced with an arbitrary mandate like this, if car manufacturers are unable to meet these limits with new breakthroughs, they will most likely either reduce vehicle weight (with potential safety consequences) or create a few token expensive car models which will not really sell, but that have sufficiently improved gas mileage to bring up their average so that they don't have to change the majority of the fleet.
2) I wouldn't call 2.23x the MPG, 'almost triple'. :)
