You can choose to redefine 'glide' as it pertains to Toyota hybrids, though I would advise against it. As I continually tell my older daughter, changing the meaning of words known to others is not helpful. It just confuses people when they THINK they are talking about the same thing you are talking about.
If you say you are 'gliding' and by that you mean running with electric power to the wheels but no ICE power, we are NOT talking about the same thing. I have seen references to emode here, meaning Electric only. The Prius crowd would refer to that as EV mode (sometimes 'stealth'. Separate from the EV Mod, which allows you to force the car into EV mode) and the names are close enough to be understood.
Glide means no power or drag from either the ICE or electric motor. It is different from coasting (foot off the accelerator and the brake) since when you coast, you are slowing down faster AND the electric motor is charging the battery.
There are a few places where I can glide (Prius glide, NO power) at the same speed I would be going in either ICE or EV. It happens that the slope of the road is just enough to overcome rolling resistance and whatever wind drag there might be at 30
MPH. Where it is steeper, I can glide AND increase speed, using gravity, not gas OR electric, to finish getting up to speed But, I NEVER slow traffic down by gliding up to speed at a less than normal rate if there is no one in front of me, but there are people behind.
The other place where glide is helpful is slowing down less quickly coming up to a line of stopped or slower cars. You could get closer, then coast, which will charge the battery, but you are using some power to get there.
And, of course, no one HAS to glide. I don't pulse and glide - the 'go faster, slow down to some speed then power back up to the high mark; rinse, repeat' P&G. I get up to speed, glide (if I can) , EV (if I can, in some rare places I force it for a short time) or just let the car do what it needs to to maintain speed. I also find the CC to be a good choice in many places.
Having never driven a TCH, I can't say if 'glide' is equally 'easy' to enter and maintain in a Prius and a TCH. It might, in fact, be more difficult in a TCH. As noted in earlier posts, holding glide CAN be very difficult and at those times it just isn't worth the effort. If you can get glide but not hold it, the car will likely put itself in EV anyway so you aren't using gas.
