all right :) fairly quickly : train lines, bus lines, footpaths and cycle paths. hubs of public transport, where people can get from their place cycling or walking (or in the worst case senario driving) to get a bus/train/tram/… to where they need to go. Room for bycicle is important (in the trains, buses, etc) so people can keep on traveling easily whem they get to their destination (and small rental cars for the few who can’t cycle or walk). Thisins not a revolutionary idea, it’s been real before we developed all our infrastructure and life around cars.
