Gear Indicator Manual [Idea]

Interesting solution! This would be the easiest since OBDII port would already have the info (but then you would need to figure way to crack the OBDII protocol). The logic should be fairly straightforward: you would only need to calculate MPH/RPM which will stay constant for each gear regardless of speed or RPM in that particular gear (unless you are drag racing with those flabby sidewall drag slicks)...

but...

Other than the cool factor, why not just glance down at the shifter? I can understand the possible need for a gear indicator for a sequential shifter, though (I often wish my motorcycles had a gear indicator)...
