Albany has a lot of the circa-1950 Crounse-Hinds of Syracuse Traffic Signals and controllers. Quite reliable, they don't always work properly in cold weather.
The controllers (shown in this video) are prone to malfunctioning in cold weather due to the grease binding up and causing 5 minute yellow lights and 20 minute red lights.
Here is some of the old traffic signals, as shown on Youtube: https://www.youtube.com/watch?v=jryVhVsYV_s
I tend to think the EV Battery Fire debacle is a whole lot of bull about nothing -- cars catch on fire from time to time, as powering them takes a lot of energy, and when you have energy you have fuel -- be in the form of the battery or gasoline. And both burn really well. But it's good they are fixing this issues now before the cars become even more popular.
I thought about getting an Chevy Bolt eventually, they might be a good car once the bugs are worked out fully. Kind of like the Corvair, which was said to be a great car by the late 1960s. That said, I have a friend whose had a few issues with her Bolt -- making random noises and other issues and GM has been a bit difficult to work with ove warranty work. My other, much bigger issue with the Bolt is it doesn't use a heat pump but only resistance heating, which means running the heat in the winter can be very taxing on the batteries, leaving to quick discharge.
