Question - getting ready to order a new P90D. I'm hoping to test out renting it out as well. Does anyone know for certain if you can lock out Ludicrous mode, or other features with a password? For example if you're letting your kid brother borrow your car and didn't want him drag racing anyone, or there's lots of snow on the roads and you didn't want someone lowering the suspension? I tried to search existing threads for this information to no avail. Thanks!
