My Camry Hybrid sometimes picks up cars in the lane next to me and a car length ahead, to match speed with them. And sometimes it loses the car ahead of it on turns. I try to aim the top of the steering wheel at the car ahead of me, and this seems to help the sensor a great deal. On turns, it doesn't accelerate, only maintains speed; can be frustrating if you want to act like a racecar driver. For example, following someone around a freeway curve at 45mph, and the other driver changes out of your lane. Despite having adaptive cruise set to 60mph (or higher), it will stay at 45mph until after the curve, and only accelerate after ~5 seconds of straight roadway. It does sound the collision alert (sadly no autonomous braking here) very consistently when I'm accelerating or adaptive cruise is on, and there's a stationary object ahead.
