Same with the swappable battery pack. Other than those two things I like it, so far.
I think the battery pack being swappable is likely to play into the Project Better Place model. If Tesla doesn't participate in that, then it is a perceived weakness of the design.
In reality, I don't think people will swap batteries often at all. If you start every day with 160 miles of range, how many times per year will you actually exceed that range in one day? Twice?
I simply don't think that it will make sense for Project Better Place to design so many battery swap locations for a process that will be so rarely utilized.
However, I could see myself getting the 160 mile range version, then renting the long range battery for a trip. 300 miles is a long way to drive in a day, so it might be enough. The longest drive I ever make is from Seattle to Whistler BC for skiing. 300 miles would be fine.
