We have to pull the key when we leave the cab, right? Well I understand why but what if someone jumped in and released the brakes?. So in the future we'll have to LOCK the cab everytime we get out. Safety. WAIT! Someone could have a spare key . The mechanics told me that one key can open up to 10 tractors. We'll have to have a spotter employee to ride along to make sure no one gets into the cab and releases or drives away with the rig. WAIT Ups is not going to do that. costs too much. That leaves us UNSAFE. Now what? Maybe install alarms and shut down systems so that an ounauthorized person does not enter tractor and wreck havoc. They'll have to install thumbprint and or IRIS readers before you can enter and start a tractor. Maybe that can be circumvented too. So, we will have to be locked in the tractor for the whole shift. When you get to the hub someone else will have to break up the set for you so you;ll be SAFE and NEVER get out of the tractor. They'll install a catheter into every driver to take care of that problem and it will be the drivers responsibility to take care of number two before the start of his or her shift. In the future. Did i leave anything out??????? What are some other safety "improvements" do you all see in the future?
