Autoblog Podcast #339

Farewell, Zach Bowman; Pikes Peak 2013; Datsun; 2014 Ram lineup
Episode #339 of the Autoblog Podcast is here, and it's the last rodeo for Zach Bowman before he departs for other pastures. The crew this week consists of Dan Roth, Zach Bowman and Jeff Ross, who talk about the astounding records set at this year's Pike's Peak hill climb, the return of the Datsun brand name and the recently-announced 2014 Ram truck lineup. Of course, we start with the garage and end with your questions and comments. For those of you who hung with us live on our UStream channel, thanks for taking the time. You can follow along after the jump with our Q&A. Thanks for listening!

Jaguar Land Rover proposes seats that scientifically massage your butt, for your health

Habitually sitting too long can degrade a person's health. Scientific research has proven that dormancy can increase the risk of obesity, diabetes, cardiovascular disease, deep-vein thrombosis, and metabolic syndrome, according to the Harvard Medical School. Although sitting can be avoided in many cases, such as using a standing desk at work, taking a seat is the only option when hopping in the car for a drive. Jaguar Land Rover (JLR) is hoping to address this negative aspect of cars with a new high-tech seat that the company says mimics the act of walking.  JLR calls the concept a shape-shifting, or morphable, seat system, and it is currently in a trial period with Jaguar Land Rover’s Body Interiors Research division. Using actuators built into the seat's foam, the seat will constantly be in motion with micro-adjustments that can be tuned to the needs of different people and body types. JLR believes it has created a system that recreates what is known as pelvic oscillation, a motion that can supposedly trick the brain into thinking the body is walking. In addition to helping to prevent internal health issues, JLR also notes that a sedentary lifestyle can degrade and shorten muscles in the legs, hips, and rear. If these muscles are worked on a regular basis, the chance and risk of injury and back issues could potentially be reduced. The new seats are just one of many car interior technologies JLR has explored. In the past, we've seen tech that tracks brainwaves and heart rates, creates augmented reality, helps prevent motion sickness, and helps stop the spread of germs. They've also taken the time to have an expert demonstrate the perfect seating position. Most of this stuff is experimental for now, but it's possible similar features could eventually trickle down to production cars, in time. See how the seat moves in the video below.

Jaguar explains the perfect driver seating position

Although the shapes of car seats are one-size-fits-all, manufacturers have created numerous ways to customize how seats are positioned in efforts to cater to the multiple sizes of drivers. Whereas old vehicles only had the options of reclining and sliding forward or backward, new cars have seats that move up, down, forward, backward, and just about any other direction. In a new video, Jaguar demonstrates exactly how to use these features to find the perfect seating position. The advice comes from Steve Iley, Jaguar Land Rover's chief medical officer. Many people only think of seating position as a means to comfort, but when dealing with posture, it can affect a person's health. Iley's first tip is to empty out your pockets, thus avoiding any impingements. That includes anything from wallets to keys to cellphones to stowed-away snacks. Before putting a seatbelt on, the driver should then make sure his or her butt is all the way to the rear of the seat and that the entire back is touching the seat. Next are the seat adjustments. Iley suggests moving the back of the seat until the driver's spine and pelvis are aligned and straight. Note in this position the driver's thighs should be resting on the seats without any pressure points. Following this step, check the distance and position of the feet relative to the pedals. Jaguar says in the correct position, the leg should still be slightly bent when a pedal is fully pressed. The driver's elbows should be in a similar slightly bent position. With both hands on the wheel, make sure the arms aren't straight and have a slight kink at the elbow. In an ideal position, the driver's shoulders should remain in contact with the seat even during turning. Last, the headrest should be aligned with the top of the head. Not mentioned in Jaguar's advice is that NHTSA urges you to sit at least 10 inches from the steering wheel — as far back as you can while still comfortably reaching the pedals and wheel — in order to minimize the potential for serious injuries from airbag deployment, and the old 10-and-2 hand position is discouraged for the same reasons. Hands at 3 and 9 or at 4 and 8 are the new norm. AAA demonstrates in the video below. If any part of this doesn't make sense, you're in luck. Both videos are helpful.
