Jeep/Chrysler's New Gearshift Appears To Be Causing Accidents (roadandtrack.com)
bartle writes: The new gearshift design for the Jeep Grand Cherokee appears to be causing rollaway accidents: 121 crashes and 30 injuries so far. The gear shifter is designed to look and feel similar to a traditional automatic gear shift lever but it is meant to cycle through the gears rather than move directly to a certain gear. A driver who is used to placing their vehicle in park by pressing the shifter all the way forward may instead be setting it to neutral before exiting the vehicle. The NHTSA is investigating.
Should we hold back progress in to protect people from injury, should we penalize the RTFM challenged individuals, or something else?
Let's make like a bird... and get the flock outta here.
Isn't that why they have an emergency brake?
My Kia won't let me take the key out of the ignition unless the shifter is in park. You're saying my econobox has more safety features than a luxury Jeep?
If you're hitting second gear in 'stop and go' you are doing it wrong.
My guess, you've never driven a stick in your life, but know you don't like them.

Correct for city driving. But this is a more recent development and it's not that much more. If you can keep the engine in the most economic sweet spot longer, you will get better gas mileage. It's hard to do that as effectively with a finite number of gears, even with flawless picking of the shift points by the driver..
However, if you are doing highway driving, the manual wins, every time.

Not true...
This used to be true because Automatics had torque converters with a slip system and Manuals didn't. Manuals lock into a gear and have no slip. Automatics have a slip mechanism that allows the car to stop at a light and not stall. This slip system also meant that there was some slip at higher speeds resulting in poorer fuel mileage in older Automatics.
However, modern Automatics have the ability to automatically "lock" the torque converter into a gear at higher speeds. This negates the advantage that manuals had at highway speeds.

In fact, a lot of the old arguments for selecting a Manual have dropped by the wayside as Automatic transmission technology has improved. There are really only two remaining arguments for get a manual, the first is that cars with manual transmissions cost a bit less and the second is that, for many, they are fun to drive... That last one will never go away...
"In Fiat Chrysler vehicles equipped with this shifter design, opening the driver's door when the car is not in Park triggers a chime and an instrument cluster alert, and the engine cannot be turned off with the car in gear"
I'm guessing "chime and alert" is a roundabout way of saying the car screams at you "hey moron, you left the car in gear!" the dash lights up like a Christmas tree.
Locking Torque converters have been the rule for a LONG time, like since the 70's... With all due respect for the guys from Car Talk, this *helps* with the efficiency, but there still is some energy losses due to the necessity of running the automatic part of the transmission. You have to keep the shift clutches engaged, that takes hydraulic pressure which implies a pump is running someplace. You also must circulate the transmission fluid to keep the various things lubricated and cool, which takes some power too. Power consumption in the transmission means less power for driving getting to the wheels.
I'm not saying the differential between the automatic and the manual is all that much these days, it's not, but if you are on the highway the manual is going to be better. Now if you want to argue that it's unlikely that your average skilled driver would be able to achieve better gas mileage in a mixed environment of city and highway driving on their manual, that for 99.9% of drivers would do better on an automatic, I can only agree with you. However, just straight out driving down the road at highway speed, not shifting, that manual is going to be hard to beat, all things being equal.

Anyone recall the Toyota driver whose accelerator got stuck (for whatever reason) and he reported he could not turn the engine off because it had a keyless ignition. Family of three lost their lives. Car makers need to avoid creating a paradigm that offers no benefit.
Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?
I own one of these vehicles, and I can attest that the shifter design is awkward and confusing. The shifter paddles are another gripe, since they're effectively useless on this type of vehicle, but it's easy to hit one without realizing it when making a turn, then you have to figure out what's wrong, and then figure out how to get it out of manual mode. And the design fails are not limited to the shifter. All the controls in this vehicle are a user interface disaster. After owning mine for more than a year, I still find it awkward, and the touch screen interface for the infotainment and climate control still befuddles me at some times and infuriates me at others. And just to add an extra special touch of irritation, the stereo automatically comes on playing satellite radio whenever the vehicle is started, and there's no way to configure it not to. I've just learned to hit the mute button every time I start the car.
The utter failure of the Jeep's user interface was really pounded home to me when I was loaned a Tesla Model S for a week and a half. The huge touch panel looked alien at first glance, but I mastered most of its functions just by poking at it for about five minutes, and everything was golden after that.
For any of you 'gearheads' this is just a reincarnation of the old school ratchet shifter. I had a 'cuda when I was in HS, a loooong time ago, that had this type and a pistol grip shifting knob. It was cool then, not really sure what I think about it now...
errr....umm...*whooosh* *whoosh* Is this thing on ?
