I have a 2011 EX with 1200 miles. This past weekend I drove a lot on the highway 65-70 mph. It was a little windy, dry and about 50 F. The car felt a little loose at those speeds compared to my 2003 Accord EX. The Accord has speed controlled power steering, it gets tighter at higher speeds. Anybody else have this experience with their Insight at highway speed. Are the factory tires an issue? MPG for a 3.5 hour ride was close to 50.
