I recently heard that, starting in June, UPS will do times studies using data gained thru GPS. They will not be "on car" at all and will complete 3-4 studies per day. Is this already happening elsewhere? Our little podunk center gets the last of everything so this could be common practice and we wouldn't know about it. How can they calculate "walks" via GPS when non-military GPS is only accurate within 12-20 feet? I love the technology, but foresee problems with this.
