Bumping this up briefly. If you are reading this, you probably know about the ~400 mile range Roadster pack upgrade mentioned in Auto Express.
Six months back, when asking about a hypothetical lesser pack upgrade for 2014 (~350 miles), the biggest group of respondents (22 of 62) indicated that price would matter and they'd likely wait before upgrading (e.g., old pack still good).
3 of 62 would do it right away without real concern for price, and 8 of 62 would do it right away depending on price.
All this suggest the rollout for a ~400 mile pack upgrade could be fairly gradual (without swamping the company), but still quickly get to 50-100 cars to get the PR word out and show off the new tech. (Upgrading a loaner roadster and letting trusted auto journalists revisit the car would also help bring the point home).:wink:
