Not to nit-pick, but the right-wing media such as Faux News would claim that they have already made the case that the Volt is a "smoking" machine -- especially its battery.This begs the question, where is the electric Corvette?
A Cadillac ELR will likely have a somewhat better performance than the Volt, but performance is how the electric car can capture a wider audience. We need some tire screeching and smoking machines.
It is called a frequency beat, the interference between the video frame rate (i.e. 30 frames per second) and the pulsed voltage that drives the BMW tail LEDs. Normally both frequencies are too high to be perceived by our eyes, however when they interfere the resulting frequency is the difference of the two, is much lower and hence visible......and why was the BMW's halos randomly blinking on and off in the video....
