Suggestion: a second Sync button, just to put the cars again side-by-side, then let them move freely. (Currently Sync makes car be side-by-side the whole time its on).
This so you can compare your hotlap to the WR in one particular corner, and see where you lost time. This can be done in the first corner, but after than, the WR car just drives away and you cant compare side-by-side (for example, cant compare where WR started braking, etc).
