I just completed a ~1600km drive back from visiting family. Half way through the outbound trip, in the middle of the mountains, I had to make a 300km detour due to a massive accident (two semi trucks head-on closed a mountain highway for more than a day). The detour was through a valley with no cellphone coverage for 150+km. At a rest stop I met a tesla driver in a panic. Without internet he was unable to figure out…

What exactly did he need internet for?

I would love to use EV - it is simpler, more torque etc. But where do we get all this additional electricity from, mostly burning carbon?

Solar, wind, carbon burning, nuclear, hydro… a mix. Petro fuel burning won't go away, it will just be a smaller part of the mix. And there's plenty of capacity at night. And there are batteries, which we can charge with for example solar in the daytime, and then use at night. Rooftop solar is great because it's near the point of use. All the people wringing their hands about the grid can rest easy, it will be fine. S…

> EVs are much heavier than their equivalent ICE vehicles. This is not true. The Tesla Model 3 is the same weight as a BMW 3 series (~3,600-4,100lbs depending on trim level). Yes EVs carry a half ton of batteries, but they get rid of the engine block, transmission, starter motor, fuel tank, alternator, exhaust system, and many other parts. Also many combustion vehicles made today are hybrids, meaning they also carry…

You're comparing a single EV that's light for it's class with a single gas car that's heavy for it's class. Why not compare the 3 series (1800kg) with the electric 3 series (2200kg)? Or compare the Corsa (1094kg) with the electric Corsa-e (1455kg)

  Nissan Juke - 3000 lbs  
  Honda Civic - 3000 lbs  
  Nissan Leaf - 3300-3400 lbs
  Honda e - 3400 lbs
  Chevy Bolt - 3600 lbs  
  Volkswagen ID.3 - 4000+ lbs

E-bikes in the EU are limited to 25km/h, 16mph. Faster vehicles exist, but they are no longer considered bicycles. In Copenhagen these vehicles (petrol or electric) are forbidden from the more pedestrian-proximate paths, like those going through parks.

Unassisted bicycles that are ridden faster than that certainly are bicycles. Which points out a huge problem with certain approaches to bike infrastructure: if you force everybody down to the speed of the slowest ones (usually small children) because there are no opportunities for safe passing, then bikes can't compete with cars for any distance beyond walking. having to go 12 km/h when you would do 30 is worse for y…

What are the main obstacle to cheap EV? Today's car are heavy as hell compared to cars made 30 years ago. Is it possible to make cars that are build on a much lighter base, but that use a heavier/cheaper battery (sodium based?)

Yeah, its called an ebike. When you are using a vehicle as large as an electric car to run your errands, probably 95% of the energy is spent just to move the vehicle around, not you or your groceries but just the vehicle to A and B. With a 50 lb ebike and a few panniers running those groceries versus a 5000lb ev, you are doing the same work but a lot more of the energy spent is going to the actual work, moving you an…
