My first car with TACC was a 2002 Infiniti QX4. Yes, 13 years ago. Since then, I've been very interested in the technology (and relatively slow improvements in over ten years). I've had other Infinitis and the more recent Ford Fusion (with automatic parking and lane assist). I'm also familiar with the Mercedes technology.
After using 7.0 today, I believe it's as good or better than anything else out there. I was able to drive 8 miles on a two lane highway with light and moderate traffic without intervention. This included stopping behind red lights (with a car in front of me), curves and hills, and flawless automatic lane changing. There is no unnecessary nagging.
My biggest gripe: When a car in front of you slows and turns into a shopping plaza (for example), the car doesn't get back up to speed fast enough. In other words, you're going 50mph, the car in front slows to 20mph to turn. When it clears, the acceleration should be more aggressive to get you back to the original speed.
But overall, it's fantastic and really a glimpse at an autonomous future. This is the first time I genuinely feel we're only a few years from viable autonomous driving. This is the real deal.
