They need to add a few more stations. On the 300 mile trip I take most often there is exactly one, and it isn't in the town we normally stop to eat at. (we commonly leave right after work and have supper 2 hours down the road which is a good time for a break). There is no station anywhere any of the hotels I stay at either.

In short, the current superchargers are a good start, but if they want to make electric cars work for long distance they need to have them at every restaurant in the country, and every hotel needs to provide a charging station.

In most of the country you can find a gas station every 20 miles even in the least populated parts. (though I can name some areas where next gas is 60 miles) Since a fill up is only 5 minutes I can fill up and then go to the restaurant across the street. With fillups taking 40 minutes we need the charging station to have a different model from current gas stations: they need to be places where humans would want to stop for a long time. Parks, hotels, restaurants, museums and the line come to mind.

It will be interesting to see what happens as (if) electric cars become common.

Fair enough, my hope is they will add in road charging on highways which removes any real range issues.

Electromagnetic induction is expencive and less efficent, but visually more apealing and fewer weather related issues. https://en.wikipedia.org/wiki/Online_Electric_Vehicle or various forms of direct connections: https://en.wikipedia.org/wiki/Ground-level_power_supply or https://en.wikipedia.org/wiki/Conduit_current_collection

However, if electric becomes the norm gas is going to have the same issues as there are ever fewer stations.
