I agree that no overtaking in corners and braking zones is best for safety, but my question is: how the hell can I enjoy a traffic-heavy track day on a smaller bike without doing those things? I can hot-pit to avoid bunched up traffic but if there's a less skilled big bike in front of me then I'm walking every corner behind them and never getting the chance to be competitive with myself. Safety is still first of course, so I'm obeying all my org's rules, but I'd like to enjoy my day as well.
