Yes, I suppose, that's what I meant. I did take my Leaf on a 180mile trip once, but I don't think it would be a great car for that kind of driving every day. But within the EV's range the EV is a great car. My Leaf still has 12 bars and has nearly 45,000 miles. And my driving distances are so short I bet I could live with less than 8 bars, maybe 7 or even 6 if I had too. This means my Leaf will likely work fine for me until the doors rust off their hinges.
ICEV's love long runs. This is why long haul commercial trucks can hit the million mile mark before needing an engine rebuild. BMW also ran a car a million miles without even changing the oil. But around town here in Colorado I've had the situation on several occasions when my temp gauge on my car never moved off of the maximum cold reading because the 2 miles trip wasn't enough to warm the engine to that point. I'd like to see BMW try that million mile test at 0*F drving the car 10 miles, then shutting off the engine and letting it cool down, then starting it up again and trying it again. I'd bet it wouldn't have made it to the million mile mark regardless of the type of oil used.
2013 SL, 40,000 miles, 12 bars.
