IMHO our innovators should be focusing on improving public transport. This is why I prefer that people live in cities rather than suburbs. You can go around without having to use your car. In the better designed cities, it's even possible to just ride a bike or walk to work.
Totally agree! American city planning is full shit, suburbs waste a lot of energy and people spend many hours in traffic jams. You must learn from Europe how to build good cities!
Yes. For me, biking is best. You get around quickly and at the same time burn some calories. I'm not sure how it would fare in tropical countries though. I mean, everyone here just want to stay away from the light. Hmm... maybe actually incorporate more green space in to cities? Maybe that could at least cut down on the heat since concrete just tend to absorb and retain it. I believe they call it heat island.
