RE: New vehicle speed controls - 2

Here is one of many TV news stories about this proposed law. What I haven't heard about yet is how the vehicle will know what the speed limit is on whatever road that it is traveling on at the time. Plus, speed limits change all the time. How will the vehicle obtain the latest speed limit? Then there is the matter of what happens if the system malfunctions or is hacked? https://www.youtube.com/watch?v=cdqTdZqpC6g

"How will the vehicle obtain the latest speed limit?"
Quite a few modern cars have safety features, such as collision avoidance, lane keep, etc. The cameras used for those purposes also recognize speed limit signs and display that info in the gauge cluster. My '21 Accord will, on a rare occasion, display a 100mph limit. Optimistic, I'd say.

I remember the old days. I had a flathead '51 Ford, my first car, which my dad bought for me for - wait for it - $150. It was totally analog, as you might imagine. Had a hole in the front right floorboard, so you could smell the leaky exhaust...aromatic! That was followed by a '57 Ford with a Thunderbird engine. I loved that car. It had a carburetor and a gas pedal that made it go fast without a TFT display to warn me I was being irresponsible. Imagine...irresponsible at 17 years of age? Really? Lots of good times at the drive-in theater with my girlfriend. Ah, the "old days"...

Yeah, technology is great, but those old days...they at least were "real".

My first car was a 1958 DKW Junior, powered by a 850cc 27-hp 3-cylinder two-stroke engine. It had a drive train that disconnected from the clutch and allowed the car to coast when you took your foot off of the gas. It also used a "thermo-syphon" coolant system with no water pump, apparently the hot water rose and the cold water sank in the coolant tank and that keep the engine cooled, at least during the winter. And of course, you added a pint of Chevron two-stroke oil with every 5 gallon fill up. The car had a steering wheel and dash made of of Bakelite plastic and rode on 12" wheels. No problem limiting speed on that car. It would just barely reach 70 mph going down hill. Definitely part of the European "old days". Maybe it was "real", but not all that wonderful. European cars got better during the 1960's and 1970's.

I figured the car got the speed limit from a map layer on Google maps. The speed limit display is not always correct.

Edit: Looks like the vehicle uses both

"Speed limit information (SLI) systems inform the driver of the current speed limit by displaying it on the dashboard and/or navigation system. SLI uses cameras to recognise road signs or use speed-limit data from the navigation system. Many SLI systems combine both."

My current car has heads-up display.

An article in my newspaper yesterday about this proposed law mentioned that when the maximum 55 mph speed limit was imposed in the U.S. during the 1970's in order to save fuel, it was wildly unpopular and eventually was repealed when the political pressure became too great for the government and legislators to deflect.

BTW, I got my last speeding ticket ever when I got a ticket for going 65 mph on my 1977 Yamaha SR500 on the freeway in a just reduced 55 mph zone. Now it seems as if the cops don't even bother to ticket you unless you are exceeding 100 mph in a 65 zone.

When/IF this comes into effect, I would expect an increase in prices of used non-restricted vehicles.

Debbie's 1997 Pontiac Grand Prix had a HUD.
She still rarely looked at the speed or gas gauge :)
