The great thing with the Seven is there are as many variations as there are owners, ultimately each to there own on styling and safety on the road, but whilst perfectly legal I don't think any of us would think of taking the ROPS off a current caterham and running bareback as being acceptable and safe. It's all about perception and understanding of the risks we expose ourselves to, both on the road and on track, For competition it's easy, we have clear standards and rules to follow which can colour our perceptions, and whilst sometimes are contencious it is fairley straightforward to review and administer. However away from competition it is more unclear, with what is acceptable only being truly only identified retrospectivly in a court of law. As James has already confirmed, he and the review team are looking at the results of the Roll Bar report and the wider track day rules and will confirm if there are any changes for the 2018 trackday season. Whilst personally if on a trackday i'd use the same level of protection I use on an event, contrary to some of the statements made on this thread and others about myself and others who are competitors, we do recognize that this is not reasonable or practical for the majority of trackday participants, and i'm sure that James and the Trackday Team will strike a balance between Safety and Practicality in the Clubs role as a Track Day Operator.
