After all my concerns about driving in rain, we found ourselves in the middle of an extreme downpour/flooding type of rain. We really didn't realize how bad it was until we heard about it on the news the next day. There were several sections of standing water on the expressway and several cars pulled over. I was not driving and STRONGLY encouraged my husband to pull the Insight over, but for some reason he kept going at a moderate/slow pace. Anyway, it plowed right through and I realized that lightness does not necessarily mean that we're going to float like a boat. Personally, I would have pulled over in any car, but I was relieved that the Insight handled as well as it did in the situation. We arrived home safely though I wouldn't recommend anyone to drive in extreme conditions. However, it passed the test.
