How about a Waze icon to warn of being passed by vehicles traveling at excessively high speeds i.e. over 100 mph? Street and highway racers are not only killing themselves but taking innocent bystanders with them. Please consider how we can help warn people that high speed idiots are approaching them. Thank you for your consideration.
Too many possible false warnings... dynamic situations that won't be valid in 5 minutes (depending on the speeding ;) . I'm not for ;)
