Interesting. I inherited from my great uncle's estate a tether car that he built and raced during or shortly after WWII. I can remember watching him race it on track in a park in Dallas Oak Cliff, probably in 1948. Although he converted the car's engine to glow plug ignition at some point, I still have the spark ignition assembly that was originally installed. Spark ignition systems allowed the car to be stopped mid-race if the operator desired. Notice that some of the antiques in the video have a stiff wire protruding from the top of the car. These wires were connected to a crude switch that disabled the ignition when somebody just outside of the track bravely held a bundled rag or some such device just above the car's path and triggered the switch as it passed by. Glow plug engines will only be stopped by brute force or fuel exhaustion.

Thank you so much for this wonderful and fantastic exhibit!! 🏁👍
