robotaxis will enable personalized trips in urban areas rather than kill ownership. so VMT isnt the measure - VMTpersonalmiles is the measure. a lower cost means VMTpersonalmiles will rise but even if it stays the same, the amount of VMT needed for the same VMTpersonalmiles will rise. simply put if avg vehicle occupancy falls from 2 to 1.5 you need 33% more VMT. to this 33% add 1.5x of idling and getting to the next ride..so effectively VMT will 2x to get you the same VMTpersonalmiles and if VMTpersonalmiles also rises 50% due to lower cost/mile then VMT has to 3x while keeping household $ outgo unchanged. so if u use your own car as a robotaxi the cost per mile will drop to 25c/mile from 75c/mile in ICE but the VMT will 3x - so ur outgo wont change and ull still prolly keep 1 gas car for the long rides and 1 AV for the urban family 1 internal personal robotaxi

The historical data realy does put a damper on the whole robotaxi replaces car ownership narrative. If Uber and Lyft at their cheepest couldn't convince people to ditch their cars, why would slightly cheeper robotaxis? People love the convenienc and flexiblity of having their own vehicle ready whenever they need it.
