> 实际情况是坐飞机比去机场开车的路上要安全的多
This claim is simply wrong.
Yes, airplane is much safer than cars--when we compare the accident rate per vehicle mile. So planes are much safer than cars when covering the same distance. Say, from San Francisco to New York, it is much safer to fly than to drive through the continent.
But if you only drive 10 miles to the airport to take a 10,000 mile flight, you can do the math and find out that a 10 mile car ride is safer than the 10,000 mile flight.
The devil is in the details. LZ just gave us an example of the danger of over-generalization.
