The title of this exercise is "En segway dans le parc", but I was wondering why it was not "À segway dans le parc", as I understood "en" is used with forms of transport we get inside like en train, en bus, en voiture, en kayak and en avion; but "à" is usually used for forms of transport that we ride or walk without physically entering first e.g. à pied, à vélo, à moto and à cheval; and I thought segways would logically fit into the latter category?
