i am parked over there 为什么= i have parked my car over there

i am parked over there 是个错句子
park作动词“停车”讲时,主语应该是人,句子应该是I parked over there. 这里不能要am.
下面是柯林斯英英解释：
2. VERBSee also: double-park; 停放（车辆）；泊（车） When you park a vehicle or parksomewhere, you drive the vehicle into a position where it can stay for a period of time, and leave it there.
根据上面词典解释,可知 I parked over there=I parked my car over there.
或 I have parked over there=I have parked my car over there.
所以推测原来那个句子可能把have误打成了am

不能去掉 这两句话的意思都是“我的车停在那边”I am [my car is] parked over there 本句省略了my car is
