Is there a way to lock the Soul EV while it is running? I haven't found a way to do it. Tried do it with the keyfob lock, then tried with a second key, nothing. On cold days like today, i want to keep the car running on the driveway to keep it warm for when my son is done his doctor's appointment. Wondering if there was a trick. I think it's disabled on purpose because it's easy to forget and leave the car running since it's so quiet.
