It is insanely fun. Its also helpful. As learners sometimes you feel something isnt right, so we swap bikes to see if either of us notice to see if its harder to shift or more difficult to get in neutral or anything, and then if the other person has no problems or notices anything thing we put effort into learning how to do it better, rather than thinking there is something wrong with the bike.
We dont confuse then. But then usually we only park for an hour or two at most before carrying on. Maybe if it was overnight it might catch us off guard.
