Until battery tech gets within a decent percentage of a gas tank. Commercial batteries are currently worse than gas tanks, but catching up fast. If they get to 20% volume&#x2F;weight&#x2F;price of a gas tank I would predict a switch is going to happen very very fast.<p>Currently commercial batteries are price limited (about the price of a gas tank + filling up the gas tank 400 times, which would keep a normal car moving for 5-10 years), and weight limited at about 5% of the energy&#x2F;weight of a gas tank. Given how it&#x27;s evolving, I&#x27;d expect another 2-3 years before the necessary technology becomes available.<p>I think 20% will be about the turning point because while gas tanks provide a 1000km range, if you can charge at home, then what&#x27;s the problem with 200km range, decreasing to 160km over 2-3 years ? Especially if you can solar charge (and combined with a house battery ... watch out)<p>And Teslas don&#x27;t count. Anything over 20000$ starting price just isn&#x27;t going to start the migration.
