"The idea of the war chariot originating on the steppes has recently been revived, chiefly on the basis of the calibrated radiocarbon dates from Sintashta and Krivoe Ozero... The present reconstructions of the Sintashta and Krivoe Ozero vehicles above the axle level raise many doubts and questions, but one cannot argue about something for which there is no evidence.It is from the wheel-track measurements and the dimensions and positions of the wheels alone that we may legitimately draw conclusions and these are alone sufficient to establish that the Sintashta-Petrovka vehicles would not be manoeuvrable enough for use either in warfare or in racing."
