Motorcycle riders can buy a magnet to sent off a strong enough field to trigger the in-pavement sensors. Seems like this car needs that as well.
Motorcycles (at least in FL) can proceed through the red light (after two signal cycles...IIRC), yielding to traffic having the green, if the sensor fails to register the motorcycle.
-or-
Buy a different car...for less money...that gets better mileage and uses regular (87 octane) instead of the high test required by the notsosmart car.

My daughter gets 40+ mpg with her 4 door Honda that seats 5 without crowding. It triggers left turn signals just fine.
