Yes, but it needs to be possible for a single car to hang with them like they can in the Cup Series now (no they can't pass them, but they can tag along behind them without help)
One of the big differences is that many of the drivers aren't just lining up. If they just did that then the 2 car wouldn't be as big of a thing. Tomorrow we will probably see a long line for most of the race, where 2 car won't be worth much until the last lap.
Looking at Danica's crash it looks like she reacted too quickly and caused herself to be spun around. She should have saved it even so. She's inexperianced so these mistakes are expected. She doesn't need to be in the Cup Series just yet.
