Re: [A/S] sway, vehicle control, and overconfidence

["bleipper" <rv@xxxxxxxxxxx>]

the faster you maneuver or the faster the wind pushing you sideways,
not necessarily the faster you are moving. Your rig wants to keep
moving just as it is, no matter how fast it is going. 

The problems with higher traveling speeds are primarily due to time to
react and the energy involved.

A slight angle on the wheels for half a second at 60 mph has 44 feet
of road to work on. At fifteen mph that half a second is only turning
your rig for 11 feet of road. At 60, your rig has sixteen times the
motion energy it has at 15 and that energy is related to the force
required to change its direction. So the higher speed means a little
bit of steering is going to have a proportionally faster effect but a
much higher force will be needed to implement that change in the
direction of motion.

The usual problem with sway and trailer towing is sway oscillation
caused by over correction and the response lags (human and equipment)
to correct the correction. This is why using the trailer brakes or
applying slight acceleration rather than steering adjustments are the
best way to handle sway oscillation. But the normal reaction to
vehicle wandering is through the steering wheel, so an astute and
prepared driver is needed. 

No problems with speed as long as you match how fast what might happen
with your speed in responding to it happening - within reason, of course.
