All cars that drive only the front wheels experience a phenomenon called torque steer: as the engine produces more power the car tends to veer off into one direction or another. This is typically only a problem with more powerful engines.
Many manufacturers will use different length driveshafts to each front wheel, maybe they'll use fancy mounting hardware, maybe they'll reduce the maximum power at low speeds, maybe they'll apply the brake on one wheel as you start to move in a direction other than where the steering wheel is pointed.
Let's say a car company put out a little front wheel drive car so powerful that simply applying the brakes or cutting power would make the car much less fun to drive. So let's say our miracle company decided to have the computer steer the car in the opposite direction when you press the accelerator pedal instead.
Then one day the dongle that determines how far you're pushing the accelerator pedal breaks. The wiper on one of the potentiometers is dirty and instead of sending no signal it's sending an erratic and inaccurate signal. It's not a problem for the engine computer, there are two pots and it's picked the good signal and limited engine power just in case. For some reason cruise control doesn't seem to work, but other than that the car seems to drive fine.
But the torque steer doohickey is using the bad signal. The bad signal is erratic and makes the computer think you're trying to accelerate rapidly and yanks the wheel to the left for no apparent reason. You yank the wheel in the other direction and the car drives fine for a bit so you continue. As you accelerate onto the freeway onramp it happens again. You yank the wheel the other way and keep going. Then you try to change lanes to pass a slow truck in front of you. It happens again, only this time as you're trying to turn left you can't counteract the insanity. Instead your car tries to make a ninety degree turn at freeway speeds.
You know that you need to break when you get close to another veichle in front. Now you have a new shiny cruise control (without latest distance keeping feature). Well, you still need to break when you get close to a veichle in front of you.
