To be honest, and this is speculation, I think it has to do with the system checks during start-up. In exotic cars, the initiating system start-up check can actually take up to several minutes in some brands/models because these machines we are driving are so incredibly advanced. That is my guess on why something seemingly so simple acts a little funny.
Regular vehicles don't really have the same type of start-up checks that goes over EVERYTHING. For example, if you look at a list of potential codes or warning lights / messages, exotic cars will have WAY more than a regular vehicle because these cars are designed to essentially be top performing machines. It has to check every single piece before moving because trying to do 200mph in something that DOESNT check itself would be a scary thought.
