Lithium ion battery technology is not a good fit with the type of vehicles we currently produce. The energy density is nowhere near fossil fuels and this implies a big battery, which also adds mass. By 2027, Land Rover and other makers of SUV will be nudging 3000kg for some of their models.
IMHO the only viable solution for li-ion is ultralight vehicles. Bicycles and Velomobiles are light enough to get decent range at speed. A bicycle used with integrated high speed rail would solve most of our commuting problems. The fact is, whether you are making tailpipe emissions or not, F=ma. Moving a 3t mass around for one person is always going to use an extravagant amount of energy and that energy has to come from somewhere.
Work from home, eat less meat, make fewer journeys, use a bike more often, make fewer children. Those are some things most of us can do.
The weight issue is why I’m looking forward to (hopefully) seeing the Aptera make it to production. Being super aerodynamic and lighter weight so that it can charge up to 40 miles a day on solar alone. Lithium batteries would be better suited for this form factor.
Take public transit and advocate for more transit to replace car infrastructure, and for neighbourhoods to be made more walkable with a more even mix of commercial and residential. The latter can literally be as simple as lifting building use restrictions to allow people to open businesses in or on the same plot as residential homes and convert parts of commercial buildings to apartments.
