Toyota "Unintended Acceleration" Has Killed 89
Unintended acceleration in Toyota vehicles may have been involved in the
deaths of 89 people over the past decade, upgrading the number of deaths
possibly linked to the massive recalls, the government said Tuesday.
The National Highway Traffic Safety Administration said that from 2000 to
mid-May, it had received more than 6,200 complaints involving sudden
acceleration in Toyota vehicles. The reports include... 阅读全帖

How long would it take to accelerate a person to the speed of light without
dying?
wolf_meister
08-08-2003, 03:27 PM
Going by classical physics
Velocity = g * time where g is the acceleration constant.
In "weightless" space, a person would be continuously subjected to a force
of one 'g' if the person were accelerated at 32 ft/sec2. Since this is
equaivalent to Earth's gravity, the person would be subjected to no undue
stress.
The speed of light is about 300,000 kilometers per second which equal... 阅读全帖

want to break.

2013 Chrysler Town and Country
Engine break-in recommendations from user's manual:
"While cruising, brief full-throttle acceleration within the limits of local
traffic laws contributes to a good break-in. Wide-open throttle in lowgear
can be detrimental and should be avoided"
我的理解是:当车辆以较高速度匀速行驶时(cruising at,e.g., 60 mph),短时间深
踩油门加速(full-throttle acceleration),有利于引擎磨合。当车辆低速行驶(low
gear),甚或停止是,要避免深踩油门(地板油)加速,因为这样会伤害引擎。这个理
解对么?另外full-throttle acceleration和wide-open throttle acceleration有什
么区别,不都是深踩... 阅读全帖

a victory this week in Superior Court in Los Angeles. A jury ruled that
Toyota was not liable for the death of a California woman killed in a 2009
