This isn’t true at all. I love Technology Connections, but Alec’s take on it is a bit misleading… They will illuminate under regen, but above a certain decel amount. This is intentional, because otherwise you’d have your indicators on constantly, so you have to set the threshold somewhere. Is it set maybe a little too high? There could be an argument for that, but saying they don’t illuminate unless the physical brakes engage is an outright falsehood.
