And yet modern software is amazingly inefficient and sometimes can be speed by 10x if not 100x - developer's time usually is valued more than performance and quality (and security) of the resulting software. Lowering of a speed limit to reduce emissions is a similar trade-off - it would increase travel time - a scare resource for many people. I'm not saying it should not be done, but the cost is far from zero.
