You're right, but MDMC's layout is (IMO) only enjoyable because of the rider position. If it were a traditional sit-down car it would be (other than the launch) quite a boring ride. The current trains are very unaccommodating - as is evidenced by the number of times an operator spiels about the restraints. Even Jet Rescue's style of restraint system would be preferable, and far more accommodating, and you could quite easily still keep the motorbike theme with that style of restraint.
But if you're going to change it then the possibility of changing the theme as well as the car opens up, so you could consider a spinner or something else to make it unique \ stand out. Being so close to new rivertown gives you the opportunity to fix the glaring oddity that is a motorsport themed ride in the middle of bushland by a river.
All fair points, but it hardly justifies 'will never be' in the scheme of things. We've seen the financials. We know they're doing things on a shoestring budget so certain things have to compromise. there are things they can fix later on when they're doing better but they're just wasteful in their current financial situation.
