Mobile techs are usually doing double duty for both local owner vehicle maintenance that can be done outside of a service center and local supercharger O&M.

I can only agree with your experience in Europe. I do not get how they do that, but Tesla Superchargers are more reliable. The occupancy information works better, they are easier to use, and they almost always offer a more competitive price. I often see other chargers that are 50 to 100 percent more expensive and only very rarely see offers that are within 10 to 50 percent.

What strikes me is that this difference can make EVs more expensive per kilometer if you only compare energy cost with fuel cost.

Here is the math with numbers. Tesla chargers in Switzerland and Germany are usually at most CHF 0.50 or EUR 0.60 per kilowatt hour at the more expensive locations, along highways for example. They offer fast charging of 150 kW or more. Alternative providers often start at around CHF 0.75 for 50 kW or CHF 1.00 for more than 250 kW fast charging. If your electric car consumes 20 kWh (Model 3 is at around 15 I think) per 100 km you end up with costs of CHF 10.00, CHF 15.00, or CHF 20.00 per 100 km at CHF 0.50, CHF 0.75, or CHF 1.00 per kilowatt hour. If you drive a petrol car that uses 8 l per 100 km and the cost per liter is CHF 1.70 you pay CHF 13.60 per 100 km.
