Sometimes parked cars get in the way of construction, there’s no doubt about it.  Those types of situations are handled on a case-to-case basis, it seems.  There are the extreme reactions, such as smashing the cars with heavy machinery to get them out of the way, or using a skid steer to move – and damage – a legally parked car.  There’s also the option to simply have it towed, reducing any liability that you or your company might have after causing so much damage.  There’s apparently also a fourth option, which is to completely ignore the area around a parked car and let the internet laugh about it.
