Nice additional safety feature. However, i dont think a lot of people are speeding on city roads at night that they won't see someone crossing the road on lit road. Disabled/elderly people also will not be walking on dark alleys late at night. I don't know the stats that back this product. May be that can establish the usefulness of this stick. Also £145 is just too expensive for a walking stick. I can buy an ordinary stick and fix an led strip on it.
