If it turns off after one second, you are not in full EV mode. If it turns off after 5-7 seconds, you are in full EV mode. It's possible your highway drive was started before you achieved full EV mode. The short stop and starts didn't allow enough time for it to get into full EV mode.
As to sitting in your driveway, I can't answer.

Larry--
You still seem to be misunderstanding, so I must be doing a poor job of explaining. I'll give it one more shot. EV mode is defined as ANY time you are driving purely as an electric vehicle. This means any time when your instantaneous FE needle is in "E mode", the blue region beyond 60 mpg. In other words, times when you're using battery ONLY, for power. There is zero requirement that you sit for 7 seconds at a stop for EV mode. ANY time the ICE turns off leaving you able to drive on battery you are by definition in EV mode.
The 7 second shutdown is what gets you into what's been called "full hybrid" mode. In full hybrid mode, which is more or less a threshold (once you get into "full hybrid" mode, you're generally there for the remainder of the trip, regardless of switches between ICE/EV driving), your car is able to _freely_ flip back and forth between ICE and EV modes on the fly, as needed. EV mode is an instantaneous/"tactical" condition, full hybrid is more of a strategic one. If you're not in "full hybrid" mode, when your ICE turns on you will ONLY be able to go back into EV mode (have the FE needle drop into blue "E mode" on the dial) by EITHER: a) (while the car is warmed up) coming down from 40-45
mph or higher, or b) (while the car is warmed up) coming to a complete stop until the ICE cuts out. These are the only ways to get the car into EV without being in "full hybrid" mode. In full hybrid mode, any time (when the car is warm) you take your foot off the accelerator and coast, if your speed is under 40
mph, it should quickly drop into EV mode WHILE driving.
Again, it is possible to be in EV mode (due to dropping from higher speed or starting from a stop) without being in full hybrid mode, but as soon as you kick the ICE on by accelerating beyond what you can do in EV mode, you will once again be stuck in ICE mode until you do one of those two things again (stop, or come down from 40+
mph). And it is possible to be in full hybrid mode without being in EV mode, because any time you hit the gas strongly you will fire up the ICE and no longer be in EV mode--but in full hybrid mode as soon as you remove your foot from the pedal (under 40
mph) you should quickly drop back into EV mode as the ICE turns back off.
And one more angle--if the ICE is on you are by definition NOT in EV mode. However it's entirely possible for the ICE to be running in "full hybrid" mode. Full hybrid mode requires the engine to be warmed up, maybe 1-2 miles of driving (from my experience), and a stop which takes ~7 seconds for the ICE to cut out, to enter. But once in full hybrid mode you should be good for the rest of the trip.
At this point if I still haven't explained it well enough I think I'm giving up, hehe.
