Hello all, I've only recently joined BMW CCA, despite being a loyal BMW consumer for the last 10 years. I know that this is a bit of a rant and I understand that the decisions are made in the name of safety, but I am having trouble reconciling that with the following: - Porsche (PCA) happily accepts convertibles at their DEs - BMW NA happily accepts convertibles at the Performance Center in SC - Mercedes (MBCA) seems to accept "hard top" convertibles at their events Given the inherent risk associated with taking ANY vehicle onto the track, how does BMW CCA justify having such an arbitrary, line in the sand rule... let alone having it delegated to the Chapter level. I've seen comments to the effect of "no instructor would want to get into a convertible in a roll-over scenario". Of course they wouldn't. Nor would they be terribly excited to get into a hard top (err, "fixed" hard top) in a roll-over scenario. Nor would they be getting in line to be involved in ANY of the vast array of mishaps that can take place on the track... All of which pose risk of serious harm to the driver and instructor. I've heard that it has to do with the insurance side of the house. If so, how does PCA manage to live with these consequences from an insurance perspective? Has anyone at BMW CCA reached out to PCA to determine how they are able to shape their insurance policies to allow for this? I've heard that despite having a hardtop, it is doubtful that the newer convertibles will hold up the same as a fixed hardtop in the event of a rollover. Has this been tested? Are there studies to show this as fact? Moreover, if there are such metrics out there, do they yield that the hardtop convertibles pose the same risk as soft top convertibles? How is it that PCA instructors are more "willing" to be a passenger in a convertible than BMW CCA instructors? I've met a few instructors (at Porsche, PCA and at the BMW Performance Center), and not once have I ever gotten the impression that they were afraid of much, let alone riding in a convertible. I've seen folks reference the idea that this is a deeply mired topic, but my question is why? Given the changes in technology (i.e. convertibles are not what they were 20 or event 10 years ago) and the willingness for other clubs to permit hard top convertibles, what are the REAL points of contention?
