Poll options spacing: You're doing it wrong.
You're suggesting that the difference betweeen 10k and 90k is just as important as the difference between 310k and 390k. Not so. Next time use geometric spacing where the next poll option is x times bigger than the previous.
[/math lesson]
I'm pretty sure I've crossed 50k by now. The car's odometer only shows up when I'm not using the segment fuel consumption display, which is very seldom.
