Don't know why you're being dv, I back this up:

- regarding my city (Paris) most sides are literally full of parked empty cars. I don't have the data but anywhere you go - apart the biggest boulevards and walkable very-inner-center - you'll see way more parked cars than driving ones. Indeed, 50% of space is allocated to cars while they represent 13% of the commutes [1].

- Vehicle occupancy was 1.5 in 2019 and is declining (US) [0].
