He has had an aggressive driving style since childhood, which led to him being involved in numerous incidents in NASCAR. Driver Derek Daly wrote that Montoya lacked technical knowledge of a racing car because he was not taught by a championship or a racing squad and needed two or three engineers to compensate for his inability to provide accurate technical feedback, which became more apparent as his F1 career progressed. He observed that the driver denied having such a flaw and frequently blamed other variables for his poor performance. Daly, however, stated that Montoya relied heavily on reflexes and intuition during his youth racing and CART career. Autosport's Nigel Roebuck observed in November 2004 that Montoya was emotionally driven and impervious to being pressured from behind.
