Buyers buy what's available and automakers comply with regulations. It's the regulations that need changing. Apparently in the US, it's easier for automakers to meet the efficiency requirements by increasing the weight of their vehicles instead of actually making them more efficient. Moreover, crash testing does not include crashes with pedestrians. The results are predictable - the rise of big, heavy, wall-like-bumper, limited visibility pedestrian killing machines.
