The faucet opened back up last night and so far today 43 cars reported getting 8.0 (2.40.21). I'm estimating that every car in the tracker represents 150 cars in the real world, or 6,450 in this instance. For all the 7.1 releases 1,023 cars reported some firmware revision in the tracker so that is my estimate of how many cars are reporting (probably some new ones for 8.0 but some old ones dropping off). 632 cars have reported an 8.0 version or 62%.
Two cars were added with 8.0 while I was writing this post
