Reply to comment by ShadowGrebacier in Study reveals that although private automobiles continue to be the dominant travel mode in American cities, the share of car trips has slightly and steadily decreased since its peak in 2001. In contrast, the share of transit, non-motorized, and taxicab trips has steadily increased by giuliomagnifico

Except now you have to add in the taxi, so it's -1 for the individual car and +1 for the taxi = net 0 / no change.

Except it's not a 1:1 ratio of taxi users and taxi cars. If a taxi covers the commute for 15 people in a day, then it's +1 and -15. It is less vehicles on the road. But.... It's more miles driven because the taxi has to get from fare to fare.

ETA: taxis subsidize the cost of car ownership, they don't reduce congestion.

Succinctly put! The only other item to point out is that between rides/fares, the taxi then drives to the next one while the personal car is parked. So they may actually increase congestion slightly. However, I'm hoping that's minor enough that its not taken into consideration for most of these calculations!

The taxi already existed though, many of them being cars driven to 500,000 miles. With the proliferation and usage of rideshare and taxi the people who would be adding 1 to the total amount of cars on the road are now not, the rideshare/taxi driver, already bought in but can contribute to as many as 100 people no longer needing a personal vehicle. It's a net loss, not a net negation. At the macro level, more cars are being taken off the road by virtue of the driver who already bought in, being able to negate a need for other people to get vehicle to begin with.

Cara on the road == cars on existence.

Cars on the road are cars that are driven at that point in time. Not parked cars
