More accidents have ocurred with pilots NOT being trained to handle crosswinds properly, than aircraft being landed in a strong crosswind with poor technique.
I teach max crosswind flying in both C152 and 172 aircraft, and it is also important to teach correct ground handling(especially so in the high wing Cessnas)
Some organistaions steer away from crosswind training, as the instructors themselves are not confident in crosswind.
It should be taught to students prior to solo cross-country flying.I use 10 kts for students for their training, increasing it as they get close to their PPL's.
Here in New Zealand, cross winds are easy to find, the wind can change within 30 minutes or so.
Cheers from the Sunny regions!
