The fact that he had such an advanced vehicle, coupled with the fact that he has a myraid of other gadgets, and the fact that Bruce Wayne disappeared for a solid 8 years. People would guess his secret pretty darn quick.
But again, it's just part of the suspension of disbelief that people accept for the character. Its the same for people not recognizing that Clark Kent and Superman look exactly the same.
