Jonathan Hanson on driving on African Savannah at high speed in Land Rovers.: It was "…like…driving across a plowed field over which concrete had been poured to solidify the ridges."
"At 100 kph we danced over them with actual tire-to-earth contact occurring perhaps 10% of the time. But the most astonishing sights were to occasional overstuffed Toyota Hi-Ace van taxis coming the other way at our speed plus, wheels pistoning up and down at an insane pace and the entire vehicle often sideways in a crazy drift around curves…the humble Hi-Ace has to be the toughest vehicle on the planet."
