Bags are used to carry lots of different things; the weekly shop, school books, gym kit. The list now includes… a car. Yes you read it correctly, a car. A Japanese engineer has come up with the WalkCar, a motorised transporter made of aluminium and powered by a lithium battery. Weighing between two and three kilograms and with the dimensions of a laptop it can easily fit inside a bag. As for transporting people, it has a top speed of 6mph and can carry people who weigh up to 120kgs for distances up to 12kms after a three hour charge. The WalkCar has what must be one of the simplest on/off buttons around. All the rider has to do is stand on the vehicle and it automatically starts moving and then jump off for it to stop. To change direction the driver just shifts his or her weight. The portable vehicle is the brainchild of 26 year old Kuniaki Sato who explains the inspiration behind his idea “I thought, ‘what if we could just carry our transportation in our bags, wouldn’t that mean we’d always have our transportation with us to ride on?’ Mr Sato is now looking to secure crowd funding so that the WalkCar can be mass produced and find its way onto the world’s streets. If all goes to plan shipping is expected to begin by Spring 2016. As for parking, well, just remember to bring the bag.
