  • You also gotta remember things also get more complicated when it gets cold. Suddenly that 40mile commute can become problematic in sub zero temperatures. Maybe you could make the trip but now you can’t do those after work errands or whatnot.

    A commuter car with 125-150mile range might be more practical as a 2nd car.

    Unless it’s an LFP car you’re not supposed to consistently use top/bottom 10-20% either reducing range if you dont want to shortern its lifespan, but LFP perform worse in cold weather so again, 100miles probably isn’t enough for that use case for a substantial amount of people in colder climates

    Edit: I checked a random website and it had 25 US states with a average winter temperature below freezing temperatures. Not considering other places like Canada or Europe either.



  • You have to plan your trips like that?

    The tesla navigation systems just plans it for you and takes that all into account. Unless you’re excessively speeding it’s almost always within 1% or 2% (over or under), and that takes elevation, speed limits above optimal efficiency, heating, cooling, I believe even ambient temperature into account.

    I’ve never ever had to think about it.

    Now, if I didn’t use the trip planner and relied solely on the displayed KM I’d never trust it, because there are so many variables to take into account. The car can legitimately get the EPA rated range in the EPA test conditions, but those conditions aren’t every day driving conditions. I would never trust if it says 400km that I’d be able to do 390km trip. There’s too many things to consider and the software does it all automatically.

    The whole making more exaggerated numbers at full vs 50% is sketchy if true, but people really should be using % vs km. Km are always going to have problems. And people should be using the trip planner for any lengthy trip.




  • This is really the EPAs fault for real world numbers.

    Real world driving conditions especially on highways where people want to get the stated range have higher speeds than what the test tests.

    If you want the EPA number to match real world speeds make the test run at real world speeds.

    If you want the population to know EVs run worse in the cold, have a cold weather test be part of the test and require reporting the number. It’d showcase how good the cars heating system is and help people make a decision.

    The EPA probably wanted auto manufacturers to be able to report higher numbers and incorrectly chose a lower speed. WLPT numbers are even worse for being wrong (but if I recall, the wrong is more consistent)




  • Instead of 1 James Webb that was super complicated to build in part due to payload size and dimension constraints, we’re going to end up with thousands of them, even further into space,

    That thing cost 10b to make because it had to work in part also due to launch costs and risks. Launch costs go down, risks go down, cheaper and more satellites go up.

    Even better than that, starship is HUGE with its 9m diameter.

    STARSHIP will be the telescope and an array or starship could be linked together. No need to design on board fuel or other navigation systems, it’s already there. Without any fancy folding mirror mechanisms well be able to do 9meter mirrors. Webb is only 6.5m

    A single starship is going to be in the 10s of millions to make. Dirt cheap.
