If I was not clear, it was in the context of the extra money and loss of mpg is well spent (value added) in traffic, IF shifting in traffic is an issue.
 
In the case of the Corvette, they have the top two gears as you describe and STILL have to drop the axle ratio and it still delivers less mpg than the manual and costs 1,100 to 1250 dollars more.

I would wager that for most of the time even the champions of manuals "here" would agree that the majority of the time they would much rather leave the driving, "stirring" to an ECU.
 
Oh God no. You would most certainly lose that wager in my case.

Yup, mine too.
 
Over the years I've lived in most of the largest and congested metropolitan areas in the United States, and I've driven (and enjoyed) a stick through them all. Errr, that is up until 2005 when finances dictated that I turn my leased car in and start using our old "Home Depot Hack" (a 1998 Dodge Grand Caravan) as my daily driver. Yes, the van was functional, yes, I could tote lots of kids and/or stuff in it, and yes, it was ridiculously reliable, but oh geez did I miss driving a stick.
 
Last fall, with the old girl fast approaching the 200,000 mile mark I finally traded her in on a 2009 Mazda3 with a 5-Speed, and to be perfectly honest, in spite of the fact that I'm commuting into Boston daily, I cannot tell you how much more enjoyable it is to drive a stick again. And yes, that even includes days when it takes me two hours to drive thirty miles.
 
Best regards,
Shipo

I own a manual and I live in Los Angeles - home of the traffic jam and auto hell on earth. I've driven both and a manual is no harder than an automatic if it's driven correctly.
 
Note - this is different than how you drive an automatic vehicle. The goal isn't to retain a close distance at all costs but to shift less and maintain a steady speed within a specific gear. This means that gaps open up and you tend to stay at higher RPMs than in an automatic. If you try to drive a manual in a traffic jam like an automatic, you'll end up tired and frustrated. Sometimes people jump in front of you and that just happens.(see a typical Semi in traffic for a reference). Though, usually, because I'm running at higher rpms, I am the one who usually gets the jump on people.
 
I've driven several miles in heavy traffic every day for years and I usually only shift maybe 5-6 times during the entire 3-4 mile section where it's bad. Usually between 2nd and 3rd, because 3rd is roughly good for 20mph-60mph on my vehicle. 2nd I can keep in as long as it's over ~2-3 mph. Technically I could start it in 2nd but the thing starts to get jerky below about 2mph...

Most People Just Can't Drive a MT by srs_49

Don't you think that a lot of the future (or lack thereof) of the MT is tied up in the fact that most (>>50%) drivers just plain can't drive a stick? Kids today learn to drive with automatics in driver's ed, take the test on an automatic (mom's minivan or Camry), and never move on to or even learn to drive a stick?
 
I still remember my oldest daughter taking her driver's test on my '82 Mazda 626 - manual. She failed the first time. The reason the testing officer gave was that she had "taken her hand off the wheel to shift". This MVA low-life had absolutely no idea what a stick was and that, yes, you have to take a hand off the wheel to shift!
 
For her re-test, we went to a different MVA office out in the boonies where we figured those administering the tests would be more likely to drive a stick. Bingo, it worked. She passed with no problems.

The issue with manual transmissions being "short" in this country is not because the manufacturers "want" or "not want" you do something. It is much, much simpler. America get top of the line engines, but the same transmissions have to support engines that have 50 horses less. For example, lowest VW Golf/Rabbit would have something like 1.2 or 1.3 engine with 80+/- horses, smallest Honda Fit (Jazz in other market) would probably have 1.1 or so, and so on. Since it is the same transmission as in our markets, no wonder 6th gear feels so short. Believe me - it doesn't when you drive those tiny engines. America is still too small market on its own to support special transmissions for those cars - hence we are stuck with manuals that crank 3000+ rpm at 80 mph at top gear.

I have actually driven (many different cars and many more different times ) in LA LA Land's perpetual traffic jams. Very truthfully over the years, I have RARELY had manual transmission issues.
 
Not that I am a glutton for punishment, but there have been times where I have strung 3/4 area traffic jams together in a day. 1. bay area, sf,south bay 2. farm land areas (believe it or not- harvest season) 3. la la land 4. san diego.

Do European models have different gear ratios? Years ago I drove an Opel Kadett 1.3L and it wasn't even breathing hard doing 160 km/hr on the autoroute. I was probably turning about 4000 rpm at that point. I had my American spec Honda with 5 speed with me over there and I was always faster from a stop, but that the smaller engine European cars would overtake me at the truly higher speeds (130 km/hr +) when my engine started to work hard.

It normally goes UN said/acknowledged that European cars are optimized for the autobahn, even a 1.3L engine and transmission (normally manual) combination. So 160 km (aka 100 mph) is about as normal as 65 mph here. As a result domestic cars are WAY dumbed down.

EXTREMES... by wwest

Driving on the Autobahn I found that I had to be more watchful and not leave my 6-speed stick needlessly down in 5th gear for long periods. The engine had enough "pull" and 5th gear was tall enough that the difference, feel, just wasn't there.
 
Here in the US my Ford Ranger I4 w/5-speed stick quickly "tells" me I need to upshift and/or downshift.
 
The thing is, with a "tall" top gear and a wide power band you can remain in that top gear from, say, 55MPH all the way UP. In the meantime the engine RPM rises from ~2200 RPM all the way to REDLINE, ~7000 RPM, frictional losses RISING all the while. Okay SPLIT the difference, 5th gear from 55MPM (3200 RPM) to 80MPH, 6th gear (back down to 3200RPM) thereafter.
 
With the power (band) of the Autobahn engine and a CVT the RPM might have stayed within 2200-2500 thereby improving my FE at the time from 25-26 to 30ish....??
 
Sorry, the math, simple math, just cannot be made to work out for a MT over a
CVT.
 
Look at it this way, with a CVT you can ALWAYS, ALWAYS be in the "TALLEST" gear ratio the engine's power band will support.
