I reckon double low gear would make traffic jams a lot easier to handle.

The only newer technology I've been spoiled by is DVD players and LCD monitors. When I got a laptop in '05 and saw how clear the display was compared to my 17" ViewSonic CRT I was like, whoa. I was reluctant to give up my first-gen Mac G3 but it barely ran and Win XP grew on me anyway. I still used CRTs on desktops for some time after that but gradually gave that up.

My 2006 Jeep Wrangler has a six speed manual transmission that seems to have a real low first gear. When driving it, I also shift through all the gears, instead of starting out in a higher gear, which is harder on the clutch.
Regarding the engine cut-off feature, there's is some gasoline-only cars out there that have it. I believe it's not a good system.
The Prius' design doesn't use an alternator or a starter. Everything is done by the traction motor and the invertor system.
There's a theory of operation found on the internet.

That sounds like the old granny gear, it's probably related to the off-road nature of the Jeep. I think it would come in handy if you were off-roading and needed to crawl over some really ugly terrain. Old Ford farm trucks with the 4 speed always had that, it's great for starting an overloaded trailer moving without burning your clutch, not so great for city commuting.

I think you might actually put less wear and tear on the clutch by shifting frequently with the engine putting out very little torque, than by starting in a high gear and dumping the clutch into a situation where it has to close under a big load - like say starting rolling in 3rd gear.

Out of curiosity, what would be a typical top speed in these very low “granny gears”? I once had an old Peugeot that would red line at 20 mph in first... seemed like a real “stump puller” gear, but I always used it to start out, rather than slip the clutch excessively.

I knew one guy who had a 1988 Ford F-150 with a 4-speed; He would always start out in second gear, probably not a good idea considering what I've read here. He also drove a fuel truck with a splitter switch so I couldn't tell what was going on there.

I'm not sure what a traction motor is; I've heard of traction elevators but I hadn't heard the term used elsewhere. There's another thing to look up.

I found this fairly recently, it's the result of someone who drove her VW Transporter everywhere in third gear because she didn't know how to operate a manual.

In an old F-150 it would probably be fine to start in second. Those were a true granny gear, and almost painfully slow to start in first.
