-1 redundant

I don't think it is redundant.

This is a more serieus poll than the poll with options like: 'personal teleporter', 'camel', 'aircraft carrier', 'space shuttle', 'magic broom', 'golden carriage'. People tend to fill in such a poll with less accuracy to pretend to be funny.

btw, what if I had a car on my seventeenth? The age to drive at 18th is not everywhere in europe.
