Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.

Grand Prix of the Americas, Day 1 Recap: a city arose in the fields, and it was good

The Circuit of the Americas is the miracle in the fields, the track that no one thought would be finished in time to hold its appointed race. But the Texans got past the turmoil, and even though the heavy machinery was still working on dirt roads as July, come November 18 there was a beautiful, and completed, Formula 1 facility for Travis County to call its own. It was dusty, sure. But it was done, and F1 could come to town.
Infiniti, sponsors of Red Bull Racing, invited Autoblog to watch the first grand prix in America since 2007, and the first GP on a dedicated F1 course since the Phoenix street circuit in 1991. Here's a little recap of what we saw and fount out on day one.

Six luxury-car features I'm ashamed to admit I love

A hot compress felt wonderful on my sore back. The methodical kneading of my shoulder blades loosened the knots that formed over several hours of driving. The Swedish-style pulses firing into my lumbar region released more tension.
I wasn't getting a much-needed massage following a recent road trip. I was getting it during the road trip.
I grew up riding in the back seat of a 1976 Chevy Nova. But once you use these lux features, it's easy to go soft.
