[edit]

This article is difficult for a non-expert to comprehend. The first sentence is "Bump steer is the term for the tendency of a wheel [OF WHAT?] to steer as it moves upwards [WHY?] into jounce. It is typically measured in degrees per metre [OF WHAT] or degrees per foot." Wheel of what? No reference to automobiles. And 'jounce' is a technical article on the fourth derivative of position with respect to time. What is 'jounce' for a car? There is no intuitive explanation of what is happening. I have a degree in physics, and I have almost no understanding of what is happening. This article is meaningless to a non-car-boffin.

The second sentence is "On modern cars the front of the tire moves outwards [WHEN?], [IS THIS COMMA SUPPOSED TO BE HERE?] as the suspension is raised [WHEN?], a process known as the front wheels "toeing out". This gives roll understeer [PARANTHETICAL EXPLANATORY REMARK OF ROLL UNDERSTEER NEEDED]. The rear suspension is usually set up to minimise bump steer, where possible."

Next "A typical value is two degrees [OF WHAT, TIRE ROTATION] per metre [OF WHAT, ELEVATION], or perhaps more, for the front wheels."

Compare this to the nice clarity of the first paragraph of the Understeer article.

I'm not a boffin. Have I improved it?. Please sign your posts. ta Greglocock (talk) 21:24, 9 January 2012 (UTC)[reply]

I'd agree; I came here from a motorcycle review trying to understand what "bump steer" meant; I haven't gotten very far. 63.78.254.2 (talk) 15:08, 11 April 2013 (UTC)shr3dthegnarbrah[reply]
