I can ride a trycicle and have slowed motor skills in my arms. However my mild is still very sharp. On my travels people like myself or with further troubles. Would get driven in a big vehicle just to bring a motorized wheelchair or other devices. Why not making a type of wheelchair they can drive right to the front like a scooter. But better, with more health considerations and a roof so they can have more freedom when still full of total clarity of mind.
