人が乗ってなくて、バイクだけ地面に転がってたので、見えなくてそれに突っ込んだようです。
ぼくらも話し込んでてぶつかった瞬間は見てないんですよね。
人をはねてなくてよかったです。

台湾では「はねられた方が悪い」ばりの勢いなんで、そこは注意したほうがいいですね(^^;)

The bike had no one on it, and it was just laying on the ground, so we couldn't see it and ended up driving into it.
Since we were conversing intently, we didn't see the moment of impact.
Good thing we didn't run anyone over.

In Taiwan, the general mentality is that "the person who got run over is guilty", so let's be careful (^^;)
