Mike,with his gildfriend are driving to home.这句话中有一处错误,请问是哪处

Mike,with his gildfriend is driving to home
把are改为is,因为主语是Mike一个人,所以用is.
如果改为Mike and his gildfriend are driving to home.这样主语是复数,才用are.
Ps：其实我们都忽视了,这句话其实有两个错误,还有一个是drive home.drive 在这儿不能加to,就像go home 一样,不能加to.
全句应该是Mike,with his gildfriend is driving home.

正确的应该是 Mike, with his girlfriend, is driving to home.
with his girlfriend 在这里是方式状语，真正的主语是Mike,所以谓语动词应该用单数，are改为 is

Mike,with his gildfriend are driving home.

Mike, with his girlfriend, is driving home.
错误处：
1. are -> is
2. to home -> home
