Most older people can't walk fast enough to cross a street in the time allotted by many automated crosswalks, according to a new British study.  The ability to cross roads safely is extremely important for older adults. "It affects older adults' health, as they are more likely to avoid crossing a busy road," Asher said.

"Walking is an important activity for older people, as it provides regular exercise and direct health benefits," Asher said in a journal news release. "Being unable to cross a road may deter them from walking, reducing their access to social contacts and interaction, local health services, and shops, which are all important in day-to-day life."

Honestly, did we really need a study to figure this out?
