This is a false alternative, because robocars do not exist, while public transit does exist but simply hasn’t been adequately implemented everywhere.
Politicians (and grifters alike) like to point to a future technology to solve an existing problem only to delay existing solutions which they don’t want to implement, most often for political reasons.
> robocars do not exist
How do you manage to discover Hacker News and not know Waymos are real? I'm truly fascinated by this new level of ignorance.
Robocars most certainly exist. They’re probably about 5% of car traffic in San Francisco. I’ve not taken one yet (taxis/ubers/Waymos are mostly impractical with a young kid in the US as you must use a car seat unlike in most European countries) but as a pedestrian they seem mostly a safer than other drivers. As a driver I expect they will eventually induce gridlock but the city can always create more bus lanes.
