Clutch pedal was depressed, shifting from 3rd to 2nd as the gear lever hit neutral there was a faint popping noise, clutch pedal froze in the down position, I sensed something wrong and allowed forward momentum to pull to the curb. I attempted to finish shifting, gears were unusable, clutch pedal frozen down. This all occurred in a half a second or less. Luckily I was in the right lane and there was surprisingly little traffic. 2 blocks further and this would have occurred in heavy rush hour traffic at 65 miles an hour. After 5 minutes of making phone calls for assistance, the clutch pedal released and I was able to slowly limp to the dealership. There were no prior signs of clutch wear except for a couple prior days in which the clutch felt a little softer then normal but so little I couldn't tell if was the new shoes or the car. The car has 38,000 miles. It is used primarily to get to work with 50/50 street and highway driving and roughly 36 miles a day. With 4 models of this brand over 20 years I have never had a clutch repair with an average life of 90-100k miles.
