I would love to come in and buy a BYD with the exact same design flaws, but for 1/3 of the price. Sadly protectionism disallows me from doing that

One of the good things in the UK is seeing how quickly my neighbours swapped out their Tesla's for BYD's. I'm not in the market at the moment so don't know what the UK protectionism position is on Chinese EV's, but has been interesting to watch how quick it's happening. I work in design and we're talking to two Chinese EV companies launching in the UK this year, so the wall can't be that high for them.

The UK has a local car manufacturing industry (Nissan, Jaguar/Landrover), but not large enough to be able to lobby for protectionism. And in any case the UK has basically given up on having a coherent trade policy since Brexit.

I've seen quite a few BYDs and MG4s, and there are Jaecoo and Leapmotor dealers near me. I've been told that some NHS boards were using MGs as "pool" cars, but the only example I can find a reference for is Shetland. https://www.nhsshetland.scot/news/article/43/nhs-shetland-ro...

I don't think I've ever seen a Rivian. The R2 is supposed to be coming to the UK in 2027.

Can and want to or being efficient are different things. I "can" travel around in a city using public transport with 3 kids and all their sporting equipment, do I want to, no. Would any sane person want to? No.

Maybe consider a sports club that's in walking -- or cycling -- distance. But I guess that's also insane. Unless you're going surfing, 3 kids and their sporting equipment fit in a small hatchback, with room to spare.

see, this is the narrow minded view of so many europeans. Well just go to a closer sports club....is not an answer to the problem that thousands of people experience with small cars, and small roads.

As a European: nice, but why is it so BIG? How is that monster called "mid-size"? Why would one want to haul so many tons of extra metal around just to transport one's behind?

As a European (dutch), why are our roads so small, that normal sized cars look like "monsters". I have often thought, that Europe will have a problem in the future with roads, as they are just too small, and expanding and making them more safe, is unlikely to ever happen and often times impossible. Not everyone can get by with a small little hatchback, some of us need a big pickup (I own a building company). And for…

Some people need more space, but the road problem is something that can't be retrofitted without demolishing buildings.

As a Dutch person, surely you've seen that Amsterdam decided that the city's car problem in the 70s was unfixable and decided to switch to cycling. The building and delivery problem is real, but I don't think even a 10 euro/day charge for work vehicles would register given how expensive building work is already.

Land in cities is very expensive. Why should vehicles get to use more of it for free?

I bought a new salad spinner recently, after having broken yet another one. I’ve had fancy brands like Zyliss and OXO. I’ve had cheap store brand models and cheaper Amazon MYSSNGVWL type stuff as well. Knowing they would probably break didn’t make it feel better when they eventually broke. Anyway the new salad spinner is large, heavy, with a steel pin into a brass bushing, has a metal handle and nylon gears in a seal…

Also if you’re dealing with sensitive information intelligence agencies can’t hack your car to go 100% on the throttle in a suburb. (Not sure if this is relevant in any way to salad spinners, though.)

Do you really need a 0-60mph time of 3.0 seconds in a mommymobile?

How much of that performance comes for free, from optimizing for range/efficiency? What's the obvious "that could be less" in the system that wouldn't negatively impact efficiency?

None of it.

It the motor is smaller, it pulls less current.

If it pull less current, you can use batteries which aren't specced for high amps.

If use use less amps, you can use thinner cabling and split the batteries up i various compartments. That means heat is more distributed. Less active cooling, if any, is needed, of both batteries and motors.

All of the above can translate to less weight, which mean better range.

Not the person you replied to, but I'm not sure how you arrived here. Brakes, coolant, washer fluid, diff oil, gearbox oil, cabin air filter, wiper blades. Did you know EV motors can also require oil changes (at hundreds of thousands of miles, in fairness)? Nice Michelins for my ICE have been something resembling 1/3 of service costs. Not 2/3 but not negligible either.

> Brakes Maybe at 1/10 the schedule of ICE vehicles, at least for me. I use regenerative braking almost exclusively (probably 95+% of the time). > coolant Yes, I did forget about that one. But frequency is about 50% less often than ICE vehicles. Maybe once every 5-10 years. > washer fluid, cabin air filter, wiper blades Agreed on these as well, but I bucketed these in the trivial category, totaling less than a tank o…

My daughter one day told me that her Tesla said it needed oil maintenance. I scoffed and tried to mansplain to her how EVs don’t need oil. Then I checked the car, and sure enough, it was asking for oil. One of the contained oil systems had sprung a leak. That’s on a 6 year old Tesla Model X.

Great, who can I contact to get this done? > What's insane about the charging port? Well it doesn't work with most charging stations. Maybe it's different in the US.

Don't they use the same IEC 62196 ports as other EVs, outside the US? They made their own in the US, because the standard SAE J1772 combo port is an unweildy behemoth, then they released the patent into public domain, and the rest of the automotive industry adopted their port into the NACS port, which beats both IEC 62196 and SAE J1772 in available power, all in a much smaller and easier-to-use connector.

Because it's the middle size between the two reasonable car sizes that are being made today: gigantic and fucking enormous.

If you aren't buying at least the gigantic car, then you don't care about your kids safety and that's bad. How are you going to protect them from my gigantic SUV?

What? Walking?? No of course that's illegal! You want to navigate the street without a massive steel bubble? Are you nuts!

I'm glad the roads are small. Smaller roads cause slower driving (well researched). As for the cities, it is unsustainable to use cars as the primary mode of transportation within cities. We do want to make cities greener and largely car-free, because cars for individuals simply do not make any sense in a city. We still need roads for deliveries and occasional transportation of heavy or large goods, but transporting…

an families with multiple kids? They should do what? Come now.

Walk? Bike? Take the bus? People had kids for years before cars were invented.
