Typical nail or screw I'm guessing. Had about a half mile "low tire pressure" warning before complete loss of air on a busy outer-belt freeway. The nail or screw was gone, but the hole was big enough the tire sealant was running out. Even maneuvering the hole to the dead-center bottom of the tire still had the sealant running onto the pavement. Someone stopped to help and went for a gas station can of Fix-a-flat. Twenty minutes later and using the extra can, it was also running out of the hole but a little slower. I was able to make it home after several stop-and-re-pumps with the air compressor.
Anyway, not wanting a random flatbed tow company to damage the front splitter, I wanted to drive the car home at any cost. Later looking into options, if I had a "mushroom tire repair plug", that would have filled any large hole well enough to hold the sealant until I got home. Since then, I bought the Stop & Go pocket plugger and the kit is really small. Just a suggestion but being stranded in a Type-S is no fun. I'm certain the emergency mushroom plug would have worked immediately.
