sorry

First of all, (traditional Chinese)對--反感（對--感到反感）/ （simplified Chinese)对--反感 （or 对--感到反感） means "be disgusted with---", "grow a negative feeling for ---.; take a dislike to --". For example, 我對公司的新規定感到反感/ 我對公司的新規定反感(traditional Chinese) 我对公司的新规定反感/我对公司的新规定感到反感（simplified Chinese), (translation) The company's new rule makes me feel repulsive. Secondly, the sentence "我對開車反感兩年了" is comprehensible for the Traditional Chinese speaker. However, it is not natural to say it like that. Personally, I would recommend changing the sentence into "從兩年前開始我就對開車感到反感。“ (translation) "I have grown a disgust for driving since two years ago. " I hope this answer will solve your question.

It means, "I have hated driving for two years." But it sounds weird, we never say so.

2 years ago, I started to hate driving.

I hate driving cars for already two years.
