Reply to comment by KingPictoTheThird 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
And yet when you do the math they increase carbon emissions in every city where they're popular - such as Seattle and San Francisco.
Did you even read what I wrote? Higher cab usage can lead to lower car ownership which means fewer cars manufactured. Manufacturing a car creates a lot of carbon emissions. In American cities, cabs seem to have mostly replaced transit trips rather than private vehicular trips. That's why you see the increase in carbon emissions. This is because our cities are so designed around cars that traveling by car, whether it is your own private vehicle or a cab, is much faster. Until that is changed, cars, whether private or taxi service, will continue to be the favored mode of transportation. All rideshare services did was lower the bar for traveling by car.
Yes, I did. And I'm telling you that they increase total CO2 emissions where they're introduced.
Yes I got that, but those emissions don't factor in manufacturing. I also told you why in the case of American cities they aren't effective forms of reducing emissions.
They do not increase carbon more than adding all the cars they replace.
Yes, they do. By 20%.

Would be interested to see what that would look like in towns that weren't laid out for everyone having a car.
How would you change it? Remember that deliveries and emergency vehicles and buses still need to get around or it's pointless - which means that in many cases you're still looking at 3-4 lane arterials at a minimum.
