Couple of recent posts on the subject, but at 50+ it doesn't happen too often.
A few weeks back :
Very strong tailwind on a flat road with with regularly spaced speed bumps,
with a kerb gap that bikes can use not to slow down. Hit 28 mph on that
stretch of the route and passed everything going, including 3 vehicles.
Doing 25 mph+ behind a car at 50+ I'm sure confuses the
driver, but they have no idea about the wind conditions.
At 50+ chasing and then passing cars / vans on the speed bumps was fun.
