The problem for them is that they can't make that long trip because the charging infrastructure is not there for them to complete the trip. The sparse charging infrastructure currently in place unfortunately is not functional a lot of times. You might start out on a trip of 400 kilometres, assuming that there is is a charging station at 200 kilometres that you can stop at for 40 minutes and have a Tim Hortons and then keep driving on, but when you get there, all of a sudden that charging station is not working.
By the way, you have to stop for 45 minutes, not the five minutes needed to gas up.
