Yep that would be my threshold for acceptability too. Legal freeway speeds to VLBW. Though my preference would also be to add "in any driving conditions (weather, terrain, etc...), with a fully charged battery". The latter was what ill-fated Coda was aiming for, and I believe with their battery pack they were probably good for it.
FWIW, even though the speed highway speed limits on the highways near where I live are 65 mph, I find myself going ~68 to 72 in my Prius. A few weeks ago on a Saturday morning, for some reason, Nor Cal felt like LA.
I suddenly found myself being tailgated going 78 mph (in a 65)
by a Yaris on either highway 85 or 17 north in the fast lane. Once I was finally able move over, one of the speed demons in a Ferrari w/no plates blew by me.
As for legal, depends on where. The limit is 70 mph on much of I-5. Nobody in a car goes just 70 mph there. Texas has some 75 mph, 80 and even 85 mph speed limit highways: http://abcnews.go.com/US/speeding-texas ... d=17549839

I'd put the standard even higher, a minimum of 100 miles @ the Interstate speed limit in any state (at least 75, with 80 preferred), from 100%-LBW with at least 10% (10 mile minimum) range reserve, in any temp between 0-40C (32-104 deg. F), free use of HVAC, and with the battery at 70% (EoL), but that requires over 200 miles of EPA range. Realistically, the only car that can do that now is the Tesla S-85, with the S-60 marginal towards the end of battery life or in edge conditions. For the 2nd gen affordable BEVs, we'll probably have to settle for 1 hour at a minimum of 65 mph, conditions as above. Even that will require at least 125 miles EPA. Boosting the requirement to make it 1 hour from 80%-LBW, as would be the case with a QC, pushes the required range well over 150 miles EPA
