Pretty sure is primarily for counting in both directions of travel without needing a second counter. Not sure they track for speed but obviously could.

First, it is perfectly fine for DC applications. The analogy never breaks down. Second, the wave analogy only works for low frequency (sub Gigahertz). Higher than that and the electrons actually behave more like particles when they jump from one conductor when traces bend to tightly. So, get your analogies…

Gah. Get out of my head, Jezza!

I don’t understand the wheel guides. If Tesla autopilot cannot effectively navigate down a one way tunnel without any cross traffic, there is noway it will work above ground.

We must have different years. On my car, pushing back makes it swipe 3 times and always activates the sprayer. Sometimes I just want one swipe. A lot of times 3 causes the dirty water to dry out and leave streaks.

Since Patrick George isn’t going to un grey me. I’ll reply to you.

I really like the flick of the wiper arm to make the front wiper clear the windshield once, but in my XC70 wagon the back wiper only has a switch for intermittent and on. To do the flick, I have to switch it on and off quick.

GMs entire design language is what killed their car sales. No one buys a truck specifically for looks, until now.  Ford must be loving it.

I thought people like truck for their visibility.  There is noway a driver can reliably see over that crest of a hood.

GMs entire design language is what killed their car line.  No one buys truck for there looks so there was little penalty, until now.  Ford must be loving this.

Duckumenatary?

Ok, I see two strong red points linked with a line that flash synchronously across miles. I would not have guessed traffic as it is a time lapse. But man if it isn’t bright to blink and reflect off dirt for miles. Now I want to know too.

We are talking AVERAGE temps not max or min. You can have a 65 (my room temp, btw) and a 32 degree night. I will still keep on the tires for the protection of ice driving at night.

What human purpose does light radiating into space serve? The lightbulb was placed for US to see. The light that shines up and doesn’t illuminate anything but the sky is light wasted in its intended purpose.

ESA too.

Yes but not entirely. That is every lightbulb that points up into the sky. This glow from all of our street lights and advertising and buildings that causes us to loose our view of the night sky. Very sad from the ground, quite spectacular and humbling to see from space.  I want to know if some one has calculated…

Good to know. Next year then. Thanks.

Most places other than the highways, plowing consists of 3 days of everyone driving while the snow melts during the day and freezes during the night.

I run mine Nov-Mar; 4 years old now, 50% tread. They are going to age out first. Rarely gets above 45F on those months. YMMV.

Agreed with your last paragraph and I can extrapolate to nominal winter conditions with the same logic you used. If you have average daily temps (high-low)/2 at freezing, you still have half of your day for ideal winter driving and only slightly compromised driving during the other half. I agree it is location person…
