"...if autonomy ends accidents, removes parking and transforms what congestion looks like, then we should try to imagine changes to cities on the same scale as those that came with cars themselves. How do cities change if some or all of their parking space is now available for new needs, or dumped on the market, or moved to completely different places? Where are you willing to live if 'access to public transport' is 'anywhere' and there are no traffic jams on your commute? How willing are people to go from their home in a suburb to dinner or a bar in a city centre on a dark cold wet night if they don't have to park and an on-demand ride is the cost of a coffee? And how does law enforcement change when every passing car is watching everything?" [link]
It seems that almost every technology changes our relationship with space.
Perhaps most of those to date have been small scale relationships, but now, autonomous mobility is influencing ideas about the physical place, placement and dimensions of urban and regional space in new, or inverted ways. It is fascinating to think about how cities became shaped around automobiles and how many or most of those urban forms and functions might become reshaped with autonomous mobility.
And while it's fascinating to think about what happens to streets (thinner?) and parking lots (parks?), it's also interesting to think about pedestrians when the on-demand ride takes you to your precise destination instead of arriving at the station or the parking deck. Are transit-oriented-developments, incentives to localization of density, a short-term wave? What, indeed will be the future drivers (pardon the pun) of density?
