有关车子方面的！

这类字眼得看语境吧……
如果是汽车方面,应该是用保险杠拖拽物体的能力吧（越野?）
再问： nascar！

The technique was initially popularized by the Archer Brothers in the SCCA Sportruck series during the late 1980s.[4] It begins as normal drafting, but the following car pulls up behind the lead car and bumps into the rear of it, pushing the lead car ahead, to maintain momentum. If done roughly or in the wrong position (e.g. close to the entry of the turn), this tactic can destabilize the handling of the lead car sometimes causing a crash. Use of the tactic in this manner is known as slam drafting. Due to the danger, NASCAR has attempted to limit the bracing on bumpers on cars, disallowed bump drafting in turns, introduced "no bump zones" on certain portions of speedways where this practice is prevalent, and penalized drivers who are too rough in bump drafting.[5][6] 从这段从维基抄下来的一段上看 Bump drafting就是允许后车顶前车 队友间可以利用后车顶前车来帮助前车继续领先 而弯道里后车顶前车是禁止的，因为会导致撞车 本来Bump drafting就只有在Daytona和Talladega可以运用 也就是说现在Bump drafting完全被禁了…… 后车由于能吃尾流所以更快，所以后车能通过在直道顶前车让两辆车速度都提升
