Yup, subsidies will be the only way middle-class Germans will be able to afford the new "normal" utility bills.
If the battery “vow” established by the Germans in 2030 occurs, it also has this unique issue. Some car companies are way ahead on design for the batteries/electrical motors. Some are years behind.
If you are a car company and your program is three years behind the rest....unless you do something to quicken the pace...you could wake up in six to eight years and realize that you will be frozen out of the German market in 2030. I think a couple of brands probably won’t be seen much in Germany as they pass the 2030 period. Course, it might also generate a market in France or Austria where a German crosses the border to buy a brand-new gas-powered car and drive it back to Germany. Lots of market opportunities are involved.
