Dire Boars have a speed of 40ft/ 6 second round.

When running that increases to 160ft.

160/6 = 26+2/3ft/second

Converted to real units that becomes a running speed of 8m/s 28.8km/hr, which, given a Dire Boars constitution modifier of +3 can probably be maintained for several minutes.

According to this website the most popular car in Alabama (Boss Hog’s territory) is the Nissan Altima.

While tragically, the Altima’s top speed far outstrips Boss Hog’s it’s acceleration certainly doesn’t, taking a whole 8.8 seconds to go from 0-100.

So while people in cars can probably pass through Boss Hog’s territory unmolested, there’s no way you’re getting out of your driveway if Boss Hog doesn’t want you to.
