For GM and Ford, building the vehicle is the easy part. At this point, they all know how to build an electric vehicle.
They definitely need to do a lot more talking. They need to normalize the idea. They need the buyers to believe that it's better. These are commercial vehicles, they need to have a lower cost of operation. And buyers have to believe it. So keep talking (and also build them).
We don't need more talk, we need better prices. Sub 30k crossovers/hatchbacks is what consumers are buying in droves. These markets aren't exactly flush with EVs or even hybrids.
If you want the average person to be buying an EV, the price needs to come down.
It should also be mentioned that loan terms for new vehicles are insane right now which is partially why the average price of new cars is so high - GM is offering 84 month, 0% loans on its trucks - today!
Often in the UK you'll see 10 or more Tesla rapid chargers with 200+kw charging rates at key locations, then for everyone else there are perhaps just two 50kw chargers which are either ice'd or broken or both.
Until people see rapid chargers they can actually use in most supermarket and shopping mall's car parks etc it is going to be a hard-sell. We're getting there slowly with things like Ionity, but it is still a rarity to see decent rapid chargers in convenient & plentiful locations.
Of course, for commercial operators this wont be a concern. but for the average joe who doesn't have off-street parking at home then they need a reliable place to refuel.
Just not an EV that's profitable that consumers actually want, or can compete with other EV's at similar price point. Tesla Model 3 being best selling car by revenue means consumers are already sold on the idea.
Do a quick search for 'van upfitter' and see. That's the market they are aiming for. What Tesla offers is completely orthogonal. Given the way that Tesla treats 3rd party repair shops, it's hard to believe that they could possibly make a serious offering in this space.
They know how to do it.
