This is a problem with bike design that nobody is talking about, the trend to market road-bikes with more sporting geometry that makes the bikes twitchy.
There is really Zero reason for a road-bike to have to steer very quickly. A mountainbike going slow in tight trails has a lot more use for quick steering geometry, but a road-bike, on roads designed for multi-ton motor-vehicles, is never going to run into turns so tight that it has to have the ability to turn any more quickly than those motor-vehicles because it is almost always going to be going much slower than they are on the same roads, get it ???
But instead of making road-bikes that are very stable, they make them very quick-steering and twitchy, and on top of the quick geometry they are making the frames as light as possible so they are not going to be as stiff as they would be if they had more material in them, and the result is the higher the speed, the less safe they are to ride.
An old water-pipe framed Schwinn Continental with very laid-back steering tube geometry, which would give it a lot of "trail", will handle better at high speed than a modern bike with "racing" geometry. Also heavier wheels are more stable at speed due to the gyro effect, super-light wheels do nothing but help in the first few car-lengths of acceleration, after that they have no advantage over a heavy wheel in most riding. And of course the fashion trend to sell non-pros "aero" handlebars used in time-trials, which give much less control than standard drop-bars, also make it hard to control a bike in an emergency.
I am sure a number of cyclists have been killed or maimed after losing control at speed on what is being sold today as a "performance" road bike.
