Evans witnessed his hopes of a maiden world title evaporate for another season last weekend at the Central European Rally.
The Welshman admitted prior to the event that his title prospects were slim, but the title fight would have gone down to the season finale in Japan next month if he'd outscored Rovanpera on the asphalt stages.
Ultimately a crash for Evans on stage 11 opened the door for Rovanpera to seal back-to-back titles, the Finn cruising through the final tests to finish second behind Hyundai’s Thierry Neuville.
However Evans, who claimed wins in Croatia and Finland, feels the title race could have been different had he not crashed out of sixth when he was leading the championship standings in Portugal.
He also believes finishing only fourth in Estonia was a missed opportunity given his speed on similar gravel roads in Finland.
“Sure during the season [I have regrets],” Evans told Autosport. “I mean Portugal, and while it was a really big crash, it was a bit of a stupid crash.
“Sometimes being brave is okay, but stupid brave is not so bright, so that was one. I think there are a few areas that we definitely could have done better.
“I look back, I’m kicking myself about Estonia because if I had the feeling I had with the car in Finland, it could have been very, very different.
