Add one more type of vehicle to the lot, and that is a self-driving mobility scooter. It's not on the market but Dr. Marcelo Ang has been in the news for demonstrating the scooter. He and others in the team at the National University of Singapore (NUS) showed off their latest model. You can consider it as ideal for phone-centric walkers who just cannot drop the phones to see where they are going, and bump into barrels and walls, if not baby strollers, in the process. Getting from point A to point B sitting down just may be the answer. Kenneth Lim for Channel NewsAsia said the little scooter travels about 6 kmph. What can the scooter do if there are obstacles in its path? The scooter has laser sensors that help in navigating around them. Lee said that it is also capable of slowing down or stopping when it detects an obstacle ahead.
