Mt Washington has the highest ever "measured" wind speed. That is because they have a weather station on top, and yes, I have been there. I bet there are much higher wind speeds where there aren't weather stations. We don't make a big deal about our cars making it to Timberline Lodge, even though it is similar to driving up Mount washington. Mount Washington also has warning signs about dangerous weather conditions. Ranier had a similar sign until it was destroyed by the weather.
That being said, I still believe the danger of Mount Washington is overrated because of its proximity to large crowds of city people who have no understanding or appreciation of the danger of the outdoors. Poor preparation and training have more to do with accidents there than the objective hazards.
