Maybe if I lived in a city and was a few inches shorter - unfortunately/fortunately the roads of rural England require you to drive up grass verges to pass cars coming in the other direction - and I anticipate this might cause the Smart to tip over .
I don't want no car thinking for me so the answer is hell no. If I kill myself driving a regular car, I'll die happy, knowing it was my own (in)decision that killed me not some smart-ass 'box on wheels'.
