Good luck hauling 100lbs of groceries through the subway.

I have 4 kids and I don't think I ever bought 50kg of groceries.

Then again, I've lived within walking distance of a supermarket most of my life, so I just go shop groceries every other day or so.

Cologne is a city with roots that reach back to the Roman empire. It has grown and developed over hundreds of years. Where would all these underground parking lots come from? Why not go a step further and demand that all roads should be put underground, too, so that pedestrians can enjoy an idle stroll on green meadors above ground without all the annoyances that come from car traffic?

>Why not go a step further and demand that all roads should be put underground, too, so that pedestrians can enjoy an idle stroll on green meadors above ground without all the annoyances that come from car traffic? I'll do you one better! Since the cars are going to be electric, why not put charging inside the road , so that the car would charge while rolling? In fact, we can forgo the battery entirely, making the ca…

I am begging people to realize that cars and trains have different use cases and trade-offs.

On the one hand, I think that ICE cars should be banned from cities, the air would be much better, and these curbside chargers look like it could help with that. On the other hand, a city filled with parked EV cars is not very different from a city filled with ICE cars. Curbside parking should be abolished or at least significantly reduced. People should just park in underground garages and walk the remaining 200m, t…

You might as well ban cars entirely at that point. The biggest criticism of EVs is that they are still cars. They are still the most resource and footprint intensive form of transportation out there.

Not accurate, short-haul flights are.

Means of Transport CO2 equivalent emissions per passenger km

Short Flight 255g

Medium Car (Gasoline) 192g

Medium Car (Diesel) 171g

Medium Flight 156g

Long Flight 150g

Bus 105g

Medium Motorcycle 103g

Gasoline Car (Two Passenger) 96g

Medium Electric Vehicle 53g

National Rail 41g

Ferry 19g

Eurostar (International Rail) 6g

Also, electric cars with multiple people manage to beat rail:

No, most US electric cars are Teslas and they use the better NACS port. Which is an open standard now. Ford will use it in the future.

There's nothing better about Supercharger connectors. CCS is now twice the voltage and supports 25% more current; the common max CCS charger power is 350KW, whereas most superchargers are at best 250KW, and often that power is shared among several stalls. Teslas use CCS2 in Europe where (ahem) they were required to, so by opening up their network, millions of cars there are out there able to use the stations since it…

> There's nothing better about Supercharger connectors.

The size, usability, and industrial design is clearly better.

> CCS is now twice the voltage and supports 25% more current

The max NACS/Tesla current is 1MW.

> The entire mass-production auto industry save Tesla has standardized on CCS1/2.

China has a different (and way crazier) plug.

I do this all the time: I bought a fold-up shopping cart with 150lb capacity, and take it on the elevator to the subway platform.

Honestly, it’s even easier than doing it by car; I don’t even have to deal with hauling bags out of the trunk, I just roll up to my refrigerator and unpack everything right in the kitchen.

Edinburgh literally has underground cycle lanes [0]

We don't need difficult to fix, hard to clean chargers in every curb. We need maintainable chargers which are gauranteed to work in some convenient location. Ideally 11kW to 22kW chargers at work and shopping places and proper fast chargers at every highway stop. This will cover most drivers needs, as daily charging is not needed. What is important is to have every location always have free charging spots, since arri…

What about a small hot-swappable battery compartment in EVs that give you enough kms to get home (like a jerry can of petrol). I'm not sure if the size of battery needed for a car would be prohibitive though. How big would a ~30km battery be?

Then instead of charging points, you could have something more like a petrol/filling station. Pop in, swap your pack, and drive off. (You could even plug the car in for a fast charge while they do the battery swap).

My model for this is the hot-swappable battery packs that the electric scooter networks in many Asian countries employ. [0]

> Cologne is a city with roots that reach back to the Roman empire. It has grown and developed over hundreds of years. Where would all these underground parking lots come from? If car parking is a worthwhile use of space, the market will provide it (and whether below or above ground is beside the point). If it's not, it won't. > Why not go a step further and demand that all streets should be put underground, too, so…

In < 10 years or so we’ll have fully self driving cars. After some time there will smaller versions that can run on smaller roads even. By that time robo taxis won’t have to park in the central parts of cities but can simply park in cheaper parking spots further out or automatic garages.

Isn't that awfully inefficient and wasteful power transfer?

94% grid-to-battery efficiency, according to this article on the SAE J2954 standard. https://www.greencarreports.com/news/1130055_wireless-ev-cha...

Nice find and that's not bad actually! Still wasteful though, it adds up quickly with the amount of future EVs.

Wouldn't some kind of dock with a flexible MagSafe-like (MacBook version) robotic arm extending from the vehicle be viable?

If convenience is the goal then there must be another solution without all this waste.
