Either these manufacturers know something we don't or they are betting on shaky future technology.
Claims that people only need 150-300 mile range (the range of batteries available today from cheap to expensive) are not only false, but incredibly disingenuous. One look at our crowded American interstates clearly indicates that electric cars with 300 mile range are impractical on vacations, long interstate trips, sudden travel needs and so on.
Stories abound about highway trips with EV's. Long charge times, slower cruise speeds to stretch range, poor heat, early charge stops due to charger locations, struggles when plans change and so on.
I love the EV's, but without 600 mile range and 5 minutes charges, there will be problems.
Furthermore, the argument that "you can just rent" falls flat too. Good luck finding a rental during season around here.
A great quote from a Chevy Bolt owner: "Like other electric vehicle owners, we are more likely to go for lunch, stay overnight, or take in local attractions while we charge up, electric-car tourism should clearly be viewed as "dollars coming into a community." down the freeway at an average of 80 mph, we got nowhere near the 238-mile rated range. After 103 miles, we showed only 70 miles of remaining range"
Like many others, your missing the story here.
No one is saying we will be 100% electric soon. However, most families have 2 or 3 cars. Only one needs long range. I drive only 6 miles to work. But even if I drove 50 miles, an electric car would be great....as long as my other half have "the more capable" vehicle. 99 % of trips are within an electric cars range. Secondly, your missing the part where batteries improve. It's not a static world, 15 years ago a battery car seemed a pipe dream, yet here we are.
