In fact, you can actually activate it while stopped, which is great when you get caught up in traffic. Works really good.
    Not true. Yes they stop but some do not stop altogether, there's smart cruise control and adaptive cruise control. Two different systems. The ones that come to a conplete stop need to have an electric parking brake.

    I recently came across an lx optima with the scc and electric parking brake which i didn't know came in an lx.

    We were talking about the SX-L, and IT DOES STOP, so it's true. Interesting that there're 2 different systems, but salesmen need to learn about that if they want to be successful. I definitely would. Otherwise you're just another among a sea of salesmen.

    If the vehicle senses another vehicle it will bring it to a complete stop based off the tracking vehicle's speed (IE - car in front of you slows to a stop). You must have two vehicles on your instrument panel showing the SCC is tracking the speed of the vehicle in front of you.

    If you activate SCC with no vehicle in front of you and you only have one vehicle (yours) on the distance meter, and you do not manually depress the brake pedal to slow down, the system will activate the autonomous braking system to avoid a collision. It cannot bring a stopped object into radar view and calculate proper stopping distance under SCC. If you come up to a vehicle that is already stopped (at a stop light), it will prioritize that as a class 1 threat to occupant safety and not a vehicle, thus emergency braking.

    Does that make sense?

    If you activate ACC, car in front or not, the car will apply the brakes (I didn't say stop) if it senses another vehicle in front. Even with emergency braking deactivated (like in my case). I tried it on a street, at slower speeds, with the range in 2. Activated ACC at the front of the stop light (automatically chooses 20 mph), car took off without any traffic in front, then switched to the left-turn lane where a car was stopped in front, and my car stopped. It's like if somebody on a freeway slams on the brakes. Granted; if you're going 60, and rely on ACC to stop for you with only 2 bars (out of 4), with a car stopped in front, good luck. Bottom line is automatic braking works when you do not have ACC activated. And ACC will stop (or try to stop) the car (at least on SXLs) under any condition. But like it was mentioned, if you're not following anybody, I wouldn't rely on ACC to stop my vehicle. It will try for sure, and maybe it does, but I won't try to find out at higher speeds. He he. By the way, when I use ACC, I always have it at 4 bars, for a safer braking distance.
