Throughout the forums, I have seen posts about this - and I want to point out that this is NOT an Insight specific issue. You can go to other sites and find complaints of other Honda models doing this as well. I am hoping that they will come out with a fix one day in the future. It happened to me today just cruising along the interstate at 70mph, and yesterday during a storm. There was NOTHING in the way, no bridges etc.. It is scary and does need to be fixed - in both cases my car did brake and I had to floor it for it not to slow down significantly..
