get in 同get on用係上車上既分別~~~

我想Andy可能記錯了，答案剛剛相反
當我們登上大型的交通公具的時候，如：bus, train, tram, ferry or plane時會用get on（但單車也用get on）；但如登上計程車，私家車等，就用get in
以下的一段引用”common English Errors in Hong Kong David Bunton”
”One gets 'on' a large vehicle like bus, train, tram, ferry or plane - and also a bicycle, where one is literally on top of it. However, one get 'in' a tax or car. One difference, perhaps, is that one bends down to get into a car/taxi but walks upright or steps up to get on a bus/train/tram/ferry/plane.
One the other hand, one gets 'in' a lift but 'on' an escalator.”

希望幫到你！

應該是用 get on，登上之意思。
Get in 通常用於對話式或相對之空間較大。

Get in the bus, 因為巴士體積大, 入到去唔一定要坐住. 所以會用on. 而Get on the car 因為普通私家車一入到車就要坐下來. 所以用get on.
