This doesn't change the amount of generation you need to go N miles. Indeed, rideshare might increase distances overall. Rideshare has some benefits in reducing some of the capital investment and some in allowing some charging infrastructure to be centralized (reducing distribution system). It might also be able to squeeze a little bit of mid-day charging in. But it doesn't really change most of the picture for the grid.

I think there is a clearly positive impact in having what I imagine would be 70% less vehicles on the road. Including the added benefit of the elimination of driveway requirements and huge parking areas allowing for more dense development and thus shorter overall drive distance. It also allows for a distribution in peak charging time. Getting people to walk would be the biggest impact.

If we move to EV rideshare, eventually houses might become closer together. But that will be a much slower effect and you'd have to deal with energy usage based on current building distances. > It also allows for a distribution in peak charging time. Already mentioned.

Rideshare is also one of a portfolio of things that make it easier to have walkable, bike friendly cities while still being able to hire cars (of an appropriate size) when necessary. So commute every workday by bike/bus/train but use a car share to get to somewhere out of town once a month.

  What I'd like to see would be transit networks aggressively build out "virtual" and "semi-virtual" routes with capped waiting times. E.g. put a "call" button at bus stops, run anywhere from no to frequent scheduled full bus routes on a stretch, and (EDIT: automatically, on demand) charter ride-share services as needed to fulfill wait time guarantees. Increase the use of actual buses as usage increases. A whole lot of transit is a chicken and egg problem where people buy cars because the transit options aren't good enough, and so have incentives to use it, and so rider numbers remain too low to justify increasing them and/or it deters people who strongly prefers to use public transit from even moving there. You need to treat it as a public good not just for those who use it, but for those who might want to use it and even those who don't but end up benefiting from less congestion and the environmental benefits, and be willing to subsidise it more aggressively, and rideshare options, with or without self driving, could help drive down the cost of operating many "bus routes" that'd be particularly expensive to operate with mostly empty full scale buses.

    Yes, transport nerds talk about why you need public transport that runs at night and weekends so that people can rely on it, but increasingly technology opens up options like you suggest. Rural areas have been early adopters of this kind of on demand public transport due to low density but it can be applied further.

    They have a concept similar to what you described in South America. In Peru you can jump in private vehicles that run particular named (sometimes even numbered) routes. The car and minibuses simply go when they are full or once they have waited a fixed amount of time and they have at least on passenger. It works pretty well and a company called CityMapper tried to do something similar in London. They looked at the transport data and found routes that people wanted to take, but we're underserved by public transport (eg. Shoreditch to Islington on a Friday night). They would then hire privately operated black taxis to run the route for a fixed fare with a fixed waiting time, and they took the risk on empty seats. https://techcrunch.com/2017/09/21/citymapper-ties-with-gett-to-launch-shared-taxi-commuter-route-in-london/ https://techcrunch.com/2017/09/21/citymapper-ties-with-gett-...
