Cecil is correct, the car will not run if the tailpipe is completely blocked. however, if you really want it to work well, core out the middle of the potato, then insert it deep into the tailpipe with a broom handle (carefully not to mash it).
The car will start and run fine. However, as soon as you press the gas down, it dies. It worked well for me to drive the gangbangers out of my neighborhood without doing any real damage. It’s also funny to watch.

No biggie, you’ll know for next time. And, as I say, welcome indeed!
I have to wonder at the wisdom of tampering with gangbangers’ cars. Glad it worked, but keep your head down.
Potato in the tailpipe? Is that what kids are calling it these days?
I’m curious how disabling their cars helps drive gangbangers out of a neighborhood. Wouldn’t that prevent them from leaving?
Now that’s funny!
I’m not sure exactly which gang bangers would sit idly by while someone watched their cars break down, cackling manically. Especially since they tend to be somewhat protective of their property.
Perhaps you meant gang members?
