Worldwide.. and that table is out of date, both catagories have increased in the new table. I can only speak to the statistics in the U.S. where ~36,000 people died according to NHTSA's FARS database. Of those, 6,000 were pedestrians. Whereas ~33,000 people died from falls or related causes according to the CDC. So, my ratio was wrong.. but I don't think it diminishes my point too significantly.

Falls disproportionately affect the elderly.. as do traffic accidents, but the opportunities for risk are typically fewer as many elderly stop driving at some point, most die as passengers when they're involved in traffic accidents.
