Hopefully they never take over the world, and we can stop this car nonsense. Having over a million extra people not killed by cars would be nice.

It's already happening in Germany and E.U. IIRC Germany set 2030 for getting rid of all vehicles with combustion motor and E.U. set the date around 2050.

Banning new ICE vehicles or banning all existing ICE vehicles?

Or street parking needs to make way for bike lanes, transit, and pedestrian space! To be honest, though, electrifying public parking isn't that outlandish either. Fairbanks, Alaska has done it for a while to power engine block heaters.

Sure, it's entirely possible but it represents a major capital expenditure for urban municipalities, probably more than most could afford without external subsidies.

In the long run it saves money on cleaning and dealing with the health consequences.

Like all infrastructure projects there is an initial outlay.

This gets mentioned a lot, but I think the point is really over stated. First, there's a huge amount of room for growth in electric vehicle adoption even if we assume that EVs are a non-starter for people who park on the street at night. The problem is worth solving, but we're no where near the point in which it's the main obstacle to further adoption. Second, cars that are being used will generally spend a fair bit…

Once you reach a critical mass of users, taking over the world will be inevitable, even with some of the inconveniences. Finding a gas station, for example, will get harder for ICE drivers as EV vehicles take off (lots of gas stations will go out of business, so you'll have to drive longer to refill your car), auto shops capable of dealing with ICE will become more scarce and expensive, etc...

At some point, the annoyance of owning an EV for some of the extreme edge cases will be less intense than the annoyance of owning an ICE vehicle. Even without proper infrastructure, the switch to an EV will be the only sensible move, even if it requires changing your habits.

Decreasing charging time might not be as helpful as you think. Lets say a car can be fully charged in 30 minutes: So the driver shows up somewhere and parks in one of the EV charging spaces and plugs in his or her car. They are not going to hang around for 30 minutes so they connect the car and go about their business. When they get back 3 hours later... This is still a problem if you can charge in 5 minutes.

Not really a problem. Putting chargers in every space in a car park is pretty cheap, they are basically just circuit breakers or even just ordinary domestic style sockets. Throw in a few fast ones for the people who need them and you are sorted. The fast chargers can be multi-head too, so even if someone finishes charging and doesn't come back someone else can still use it. Most rapid chargers are like that. Also, if…

Charging a car requires a nontrivial amount of electricity, so it's not sufficient to add a circuit breaker / socket, you also need a payment infrastructure unless e.g. the municipality is willing to sponsor the energy costs of everyone driving.

Half the range is really a non-starter. And is that range a "best case" range with ideal weather and new batteries and all down hill, or is that a worst case when its 20 below and the batteries are 5 years old? What's the minimum guaranteed range? Having to have the car tied up to a charging station for long periods of time just to do normal kinds of around-the-town kinds of trips - also a non-starter. Can you imagin…

I’ve seen work electric vehicles advertised that let you plug your electric tools in. No battery powered tools required and no generator. However not all tools are better when attached by a cord - my lithium ion drill is incredible.

I agree the new tools are incredible. Their planned obsolescence interval seems to be a lot shorter, though.

Parking spaces in dense areas already act as a huge subsidy toward cars, so I don't think electrical cost is a deal-breaker.

Or you glue on half a parking meter to turn the electricity on and off.

> Drivers will have to shed their attachment to the sound, smell and feel of gas-powered engines. I for one will not feel the least bit sad when continuous, smooth acceleration becomes the norm, and lurchy, awkward automatic transmissions fade into distant memory. I'll probably feel slightly nostalgic about the sound and smell of fuel-burning cars someday, but it won't inform my buying choices in the slightest.

I wonder if there will need to be a replacement noise given to electric cars for safety reasons. Will they all have to make a fake broom-broom noise, or will some other noise be chosen? Maybe they'll be silent until they detect pedestrians or in built-up areas.

IIRC many places already have a legal requirement for replacement noise for safety reasons, usually the criteria is that it must be active below a certain speed.

Almost all of that is the battery. Even though batteries are coming down in price, they are still very expensive. For example GM’s list price for the Bolt battery is $15,734. Now this is the replacement cost Bolt owners pay for a new battery not the actual cost, but it gives an indication of their cost. https://electrek.co/2017/06/12/gm-bolt-ev-battery-pack-price...

How much power does the electric motor need? -edit- found it https://www.quora.com/How-much-power-is-required-by-the-moto... 80kw to accelerate and 1 kw to maintain. -edit 2- how come no ones put 3 solar panels on top of an EV? Three of the following could output 1 kw and fit in the space available. http://www.solarwholesale.com/wp-content/uploads/2016/10/Sil... Seems like an obvious for electric semis where there’s…

1kW to maintain is nonsense. My 11kW limited motorbike (much lower air resistance) can barely do 65mph, sometimes hits 70 on a downhill. Any wind and you won't break 60.

It seems like Tesla is at least hinting to aim for a system where you can basically send your car out to charge and have it back when you need it. Combining auto pilot with this prototype, it is at least feasible that it could work https://www.youtube.com/watch?v=uMM0lRfX6YI
