I would guess that 24 mph is the threshold at which the accurate detection performance of the system falls below the level at which Lexus feels is sufficient to claim that it "works." Above those speeds, the system might work, for example, 92% of the time instead of 99%.

1) I think at least some of these systems are designed with an accelerator override - if you lift off and depress the gas again, it will cancel the braking action. (And if they aren't, such overrides might be coming)

I just saw an ad today for a BMW on craigslist that said it had a "straight V6". *Faceplam.

Let's be honest. The X5 might be more fun to drive, but if you're buying and planning to keep the car for 10 years, which will have lower total cost of ownership? Which one will start every day? People who buy these mid-size SUVs have kids so that some part of their life can be difficult, they don't want a car to add…

The Model S (and, I'd argue, all electric cars) do make an awesome Starship Enterprise sort of sound. It's not strictly an exhaust note, but it sounds cool, and it's best when it's not muffled by sound deadening, like in the cars built by university students (skip to about 0:34).

The reason (as other commenters have noted) for the quivery voice and likely the 911 call is adrenaline. As Clarkson would say: "oh, a lot of poo just came out!"

You have to keep in mind that in Russia, the dashcam video is needed as evidence so you can get your insurance/the courts to support your case when you're not at fault. For that reason, it's probably worth spending the money to get clear, high quality video. In the US, the police report, your testimony, and any…

Most interstates here are not in flawless condition, but it varies a lot by state. Don't let appearance fool you, sometimes the roads are in decent shape but look bad because they've been spot repaired extensively. I'd give US interstates (motorways) a generous 7/10 – a passing grade but only just.

This should be the only option.

They are in the left lane going 58 with every other driver in Seattle. Meanwhile, the right lane has one car about to exit. My mom, otherwise a very good driver, regularly sits in the left lane on I-5 because she is "going faster than the other drivers" (read: going 63).

How will this car fit with the brand? Waterfall grille, ventiports, job done.

I don't know about the attorney part, since there are plenty of high-flyers who take Metro because it's less stressful than driving and, if they are within the snow operating area, safer than driving during snow emergencies if they have to go into the office. That being said, people who work long and weird hours (e.g.…

This gets back to the problem with electric cars being a solution to every environmental problem. They aren't and, in fact, could be worse for congestion as they make people think they can skip mass transit.

Because everyone has a favorite car that is actually a dog, objectively, and they don't like it when CR calls out their favorite car for being what it is, a stinking pile of crap when it was sitting on the dealer's lot with 4 miles on the clock. As a result, they say that CR reviewers favor boring Japanese beige…

There are so many epic failures from GM, it's hard to pick just one., but I'm definitely going with the Cavalier.

Maybe not the best car GM has ever made, but not even close to the worst. Build quality, styling, safety, and features are all at least adequate. GM has made so much garbage over the years, it's not hard to think of better answers than this.

I also love cloth seats. Cooler in the summer, warmer in the winter (without some seat HVAC system that is bound to break and cost a fortune to fix), and they hold you better in the corners.

Witnesses are notoriously poor about remembering details. Unless it was a not-street-legal dirtbike without a headlight, I'm not aware of any modern bikes that don't have a light that turns on with the ignition.

This is a reasonable theory, but a lot of these systems, or at least their airport stations, are actually quite new. Of the ones I was able to think of, only ORD, ATL, and DCA had their stations completed before 1990. Since then, MDW (1993), STL (1994), PDX (2001), SFO (2003), PHX (2008), SEA (2009), MIA (2012), and…

At Frankfurt and Munich, there's direct high-speed rail service, let alone local commuter rail (S-Bahn). For reasons that are entirely unknown to me, it seems to be a big challenge in America. Among cities that have some sort of rail rapid transit, there's direct-to-terminal service at just a few: SFO, SEA, PDX, SLC,…
