Impractical on so many levels: - You have to bend down to use it- not good for grandpas or other people with accessibility problems. - Water and grit ingress will be a problem. - In Winter it will be covered in snow - The gravel they spread on the sidewalk will scratch the glass in no time. - When it is wet it will be all dirty and nasty. - Will have to withstand cars stepping on it and wheels rubbing against.
Yes lets second guess German engineering.

100 pounds! We'll need at least 2400 pounds of automobile to handle such an unweildy load. I jest but people handle shopping in a myriad of ways, if you live somewhere with good transit it's really not an issue. The Big Shop is a bit of a symptom of suburbia's unavailability problem anyway, since it's such a pain in the butt to get groceries I would optimize it all into one big shop with the car. It's really similar…
It's super easy to get groceries where I live but I still wouldn't want to go shopping multiple times per week. I'd rather spend time on other things.
Costs 0€ if you're not a stickler about the delivery window and order for at least 50€ at a time.

> 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…
If parking would be left to "the market", no one would do it within city limits. Parking spaces are heavily subsidized. In Germany, until recently the costs for a residential parking spot were capped at strong 35€/year or so. The actual "market value" of the equivalent space in cities is often around 4000-6000€/year. Getting cars out of cities and using the space more efficiently for pedestrians, cyclists and public…

#164We 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 c…

Your figures don't add up. Divide the electric car by 4 or 5 and it's still more than the electric Eurostar train, and that's a high speed train too.

Every new development in my city already includes underground parking. The cost of land in the city is way too high to waste it on parking lots. They are also building lots of underground garages everywhere. I don't know what they do about power lines and sewer lines, but they seem to have figured out a way to do it, considering how many garages are being constructed. Removing curbside parking would provide some addi…
Think about the environmental impact of digging-up and constructing massive underground parking caverns. I haven't done the math, yet, I have done a lot of construction projects of various types. I can assure you that building underground parking structures is probably one of the worst kinds of projects in terms of environmental effects. Not just CO2 generation. Absolutely everything conspires against you for such a…
Obviously cars are environmentally a disaster, but people like them too much to give them up altogether.
But if you drive a car, the least you can do is park it somewhere where it isn't taking away public space. (Parking cars are also in the way of other cars that try to get somewhere)

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.

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.

Yeah but it still beats the other trains, which is very surprising. Also my second link has more info. I’d prefer better sources on all of this though.
That splits the figures into 35.2g / passenger-km for electric, and 704.4g for diesel. The per-vehicle-km figures have a 1:3 ratio, but the per passenger figures nearer 1:20, so I think the huge disparity is due to electric trains being on much more heavily used lines. With Eurostar being 6g, they must have very high usage, or maybe the older electric trains really are much less efficient than the newest ones.
