1.都可以.
1)I saw no car in/on the street.= I didn't see a car in/on the street.
我在街上一辆车子也没有看见.
2)I saw no cars in/on the street.= I didn't see any cars in/on the street.
我在街上什么车子也没有看见.
2.但是,如果做no car和no cars做句子主语时,虽然句意类似,但是其谓语动词的数不一样.
如:No car WAS in the street.
No cars were in the street.
3.另补充说明,in the street和on the street都是可以的.
