The Audi Q7 doesn't want me to speed and I'm not totally okay with that

I'm a big fan of adaptive cruise control. My commute is 50 miles each way, almost all on freeways here in Michigan. If everyone drove at the same speed there'd be little need for smart cruise, but I live in reality where people camp out in the left lane and practice going from the gas to the brake for no apparent reason. Radar cruise systems let me set my max speed and just worry about steering. But Audi has gone a step further with its adaptive cruise system. And it's a step I'm not sure I'm comfortable with. Audi's system, as featured on the new Q7, has a feature that uses the forward-facing camera to read speed-limit signs, something that's becoming common in Europe and is now making its way here in the continent's luxury cars. That part's fine; it's useful information and gets nicely integrated into Audi's Virtual Cockpit screen and on the head-up display. What the car then does with that info, however, is the issue: If your set cruise speed is higher than the speed on a sign you pass, the car will drop the cruise speed down to the limit. But it's not perfect. On one stretch of highway, the Q7 picked up the speed limit posted on the parallel service road, dropping me down from a little above the limit to 30 mph. It didn't slam on the brakes, but it did confuse me at first and require intervention before the car slowed down to a crawl. This feature isn't ready for primetime. Luckily, it can be turned off or switched to a mode where it gives you a warning that the speed limit has changed (or at least that the car thinks it has) and lets you react before the set cruise speed is changed automatically. When activated, it's a safety issue. A more serious one, in my opinion, than driving a little over the speed limit, especially when it means interrupting the flow of traffic. There's nothing predictable about a car trundling along in the fast lane and then completely letting off the gas. It's not predictable for the driver behind you, and it's not something a driver expects of their own vehicle. Yes, this feature was obviously developed for people driving on the Autobahn, where speeds can drop down from unlimited to a slow crawl pretty quickly when entering a construction zone or approaching a built-up area. German roads also have more consistent signage, so the false-positive scenario I experienced might not have come up there.

With increased range, Audi R8 E-Tron revving up for production. Maybe

As Tesla Motors proved mightily in 2013, an expensive EV with a long range can sell quite nicely, thank you very much. Perhaps Audi was taking notes, since its all-electric R8 E-Tron's on-again/off-again odyssey appears to be on again, according to UK's Autocar, citing Audi's Urlich Hackenburg. The model is near the approval stage for production, and the key to the green-light is the fact that its single-charge range has been almost doubled to 250 miles. The R8 E-Tron gained kudos in these parts last June by turning in a rather brisk 8:09 time around Germany's Nurburgring track, a record for a production electric vehicle (check out the really quiet video here). Still, plans for the 376-horsepower model, which has two electric motors and was first shown off at the Frankfurt Auto Show in 2009, had been put on the proverbial blocks largely because of a relatively short single-charge range of about 150 miles. Then word came out last spring that Audi would produce maybe 10 units before reports from Australia's Drive late last year indicated that plans for potentially broader production were being resuscitated.

Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.
