Re: Deer may be worse in the US because of what's around our roads
They weigh similar to an adult male human and can move at over 10m/s+. They are unfortunately coloured making them very hard to see in the first place, especially at dawn and dusk where they are most active. They can and do change direction on a dime making appropriate evasive action difficult to determine. The only real way to minimise chances and reduce collision severity is to slow down at those times of the day. They tend to congregate in flocks (called mobs) so if you see one or two in a short distance then slow down.
