The effect of this would be that each wheel would be pretty well left to itself in going straight ahead, but they would move together in steering, each wheel setting itself at its natural angle to the car. When the wheel in contact with the ground was wrenched round as you describe the rotation of the other pivot would be the reverse of what it is at present. As far as I can see violent wobble due to tramping would be impossible with this gear. (Low speed wobble might be fierce. They are obviously contrary effects because a wet surface which cancels high speed wobble, makes low speed wobble much worse.) (4) An improved Lovejoy front shock absorber, with more "velocity-effect" in the valves. Am seeing Lovejoy tomorrow about this. He is very anxious to equip our cars front and rear and in fact some of our owners are insisting on it. (5) Criss-cross shock absorber on front axle. This need not affect the suspension (as sketch), but probably a tremendous lot of friction would be necessary to stop criss-cross motion by direct means like this with so little angular motion.
