Here in the SF Bay Area people have one of the highest commute distances and traffic problems in the US. A lot of the smaller pure EVs might not last those round trip journeys.

I remember seeing a cartoon more than half a century ago with a pair of pilots in a cockpit and a notice "Break glass in case of emergency". But today on my Dutch radio station someone remarked that soon people would be unable to park in a car between a pair of them because they would be used to leaving driving to the car itself and wondering if pilots nowadays get enough experience to be able to handle an aircraft in case of necessity because the aircraft can take care of all routine flying.
Electric cars will not be mature as long as they need to carry large and heavy batteries. Either use fuel cells or use antennae in the road to deliver energy to the car in the way used by a bus in South Korea on a 14 kilometre route. The second allows the car to follow the antennae so it doesn't need a driver.

EV vehicles running without batteries and using antenna is nothing new Electric trolleys date back to the 1890's. EV vehicles with batteries and or Fuel cells are a necessary evil. In and around cities like Beijing or New Delhi they could do wonders in reducing the localized pollution generated by commuting. Of course larger scale industrial sourced would remain a major issue.
Trolleys and streetcars using overhead wired for electricity feed are decidedly awkward as they are apt to be hit occasionally by high or high reaching vehicles. The Korean bus has its feeding antennae built into the roadway.
There is another method in which a short conductor under the vehicle is electrified. I recently saw that it is used by a tramway in Bordeaux. It was first employed more than a century ago by a tramway in Prague.

Sure that's all fine and good for a bus that runs a fixed route but what happens when the driver takes a side street or leaves the charging lane? It reverts back to the battery. I mean that's what your Korean bus is doing charging the battery via the same means as a charging station.
The Bus still has a battery after all what happens if you have a brown out? The bus would stop without a battery.
the point of a Plug in personal EV is that it's a car that will not pollute like a regular car. so you have the independence of a personal car yet lack the stink. if you try and run a car on a wire you lose the freedom of the car. Sure you could include such charging corridors on regular commuter roads but not all of them, Oh And remember although The Us, Europe and Major Chinese Cities have reliable power grids Most of the Developing world lacks such.

To have freedom of movement for any EV vehicle working of an antennae arrangement, one will need a system like the fairground fun electric bumper cars.

Exactly the investment would be untenable and the ability to construct such unreliable. So EV's need Batteries or Fuel cells and charging stations and if you want your wired streets fine but your only going to get some of the roads.
