The problem is very much political with a move away from highways design focusing on strategic mobility, the movement of people and goods over long distances, to sustainable mobility, the movement of people over short distances (0-5 miles) and the provision of systematically safe infrastructure https://www.youtube.com/watch?v=5aNtsWvNYKE
It's a really really hard political problem to solve as the impacts are measured in decades but the returns are huge.
From a technology point of view, the solution is the bicycle.
Focusing on the bicycle, there is huge effort going into electric bicycles around battery and powertrain technology Ebikes enable people that would not cycle in 'hilly' cities to use bicycles as a way of getting around.
The key problem however always comes down to the perception that the roads are too dangerous and this is a political in nature usually requiring the re-allocation of road space from parking.
