Questions & Answers about watashi wa kuruma o unten dekiru ga, chikatetsu no hou ga hayai desu.

Why is the particle は used after 私?

は marks the topic of the sentence. In 私 は, it tells the listener “as for me,” we’re going to talk about what I can do.

Why is 車 followed by を?

を marks the direct object of a transitive verb. Here, 車を運転できる means “(I) can drive a car,” so 車 is what you’re driving.

What’s the function of できる in 運転できる?

できる is the potential form of する (“to do”). When attached to a noun+する verb like 運転する, it becomes 運転できる, meaning “to be able to drive.”

Why is が used here instead of けど or でも?

が is a formal conjunction meaning “but.” けど is more casual, and でも can feel slightly stronger or more emphatic. In written or polite speech, が is often preferred.

What does のほうが mean in 地下鉄のほうが速いです?

It’s part of the comparative pattern AよりBのほうが… (“B is more … than A”). Even without explicitly restating 車より, the sentence implies “the subway is faster than driving (a car).”
