I have raced since the end of 2010 and never seen a people's curse as in car get destroyed by heavy equipment. They used to hand out ballots at the races, but hardly anyone would vote.
I voted one time, because a certain team was driving like complete a-holes. I believe the curse for them was a 3 hour park job.
The only other curse I remember seeing was that everyone got to come up to the cursed car with a wrench and remove one part from the car. I did not take part unfortunately, because that curse is funny to me and does not totally destroy a car, just makes the team have to thrash it back together.
And then there was the rx7 team in Sonoma who had radios on the police frequency, which delayed the start of the race, they got the people's curse even after they bought a bunch of free beer that Saturday night. Their curse was that every piece of their engine had to fit into a cardboard box the judges found, so they cut it into strips, taped it together, made a giant ring of cardboard, and drove their car through it, ingenious, then they were allowed to race again.
Pure speculation, but I am guessing that with the added cost of the safety equipment and investments in these cars on average of $5000 to get them to the track, people did not have the heart to destroy another person's car. Most likely the ballots probably just became a pain for Lemons staff to deal with and they finally determined it was not worth printing them up.
