I think the only transistors in my coupe are in the radio and maybe the turn signal circuit. Everything else is fuses or relays, and I am keeping it that way.
After the upcoming High Altitude Electromagnetic Pulse attack by our enemies du jour I will be the only one driving around. The highways will be empty, cellphones won't ring, and parking meters in the city will be inoperable. Like an endless week-end. Even bills will stop coming. Neat.
When the water runs out in CA afterwards, my Corvair with points will still soldier on.
