Again, locomotive has been electric drive motors for decades and decades..with diesel generators to power them. Their limiting issue has been power storage (AKA batteries) and an electrical controller capable of handling that kind of current.
Bullet trains solved that storage issue with live wires or rails and are all electric. Heck, even the mag-lev bullet trains are all electric but not rotating motors.

Just because the distribution system isn't there yet...does it mean the technology isn't any good...
History repeating itself...and those who either do not know of, or educated thereof are destined to repeat those historically based learning points...
The issue is not the distribution system. The distribution system already exists for just about every house and commercial building in the USA.Yes, but limited in most, unless rewired with +50 amp and higher than standard 110/120. Maybe tap into the dry/stove line.
Standard 25-30 amp line will limit charge rate, but slow charge is the best...these higher rates reduce Lith-Ion life and most other battery types on line now
Or on a trip...try stopping at someone's house and ask them if they will allow you to plug in to recharge for a few hours and then continue on your trip...ask if you can use their rest room... :B
Go back and read up on the Graphene batteries and better yet would be capacitor batteries
The issue is that batteries are expensive, hold very little power (relative to size and cost) and they take a long time to charge (even with the high powered chargers).Again, go back and read up on the newest types of battery IP
Your comment is based on lead acid and Lith-Ion types
Capacitor batteries will charge fast and can be employed as regenerative braking...where as Lead Acid & Lith-Ion can NOT absorb the regen power fast enough...can be designed to...but that would mean lots and lots and lots of them in parallel to do that...well...but sizing and weight will become another issue wit the size of cars they use today...why said full sized pickups/SUVs best for now
The idea that it is foreordained that electric will take over because gas took over from horses is false logic. Gas took over because it was better. In fact unlike electric which receives a lot of positive support from the govt and still struggles to sell. Gas cars had the govt fighting the adoption of mass produced cars.If you have access or the inclination...look up all of the OEM's road maps...not the typical bean counter 3-5 year plans, but 10 or more years out.
Plus check out some countries plans to ban ICEs and replace with electric in the near future
I think electric cars will do OK once people get over the idea that they are fully functional the same as gas cars. If you are commuting 10miles to work and have a 2nd car, they should be able to produce a basic commuter electric car for comparable price to a gas commuter car but if you need a car that can go 200-300miles (and not come home to your garage at night), it starts becoming a big hassle to try and make electric work. Even if high power chargers become more common, high power means a half hour for partition charge and longer for a full charge and 200+ mile range means you are paying 30-50% more for the equivalent car.Buddy lives south of Watsonville and commutes to my area...Silicon Valley since the early 90's and drives an old 80's VW Bug that he converted to all electric with lead acid batteries in the trunk, rear seating area and even in the engine bay
About 150 miles round trip without running errands. With errands just under 200 miles
Around 2010, he bought a Prius and added about 500 lbs of Lith-Ion batteries from Zero Bike (Santa Cruz) and now has about 500-600 mile range...
He is an engineer and we noodle Capacitor Batteries all the time and the issue is that the controllers are not there just yet. They have them for bicycles and motor bikes but the amperage is too small for a car to have the power needed for our performance needed/desired and regenerative braking
