I saw a number of Tesla vehicles on the road as well, each passing these same emergency vehicles, but not always in the same lane.
By this point, there must be 1M+ incidents of Tesla vehicles passing roadside emergency vehicles in an adjacent lane.
12 crashes is 12 crashes too many, statistically speaking, but it's also a tiny tiny percentage of the total number of cases.
IMO, it is good that there is federal investigation into this. My main concern is that is seems our government agencies at large are not very good when it comes to properly understanding anything technology related, or making relevant decisions/rulings/etc. on these kinds of things.
