What is the author's TONE in the following passage? Almost no feature of the interior design of our current cars provides safeguards against injury in the event of collision. Doors that fly open on impact, inadequately secured seats, the sharp-edged rear-view mirror, pointed knobs on instrument panel doors, flying glass, the overhead structure-all illustrate the lethal potential of poor design. A sudden deceleration turns a collapsed steering wheel or a sharp-edged dashboard into a bone-and-chest crushing agent. Penetration of the shatterproof windshield can chisel one’s head into fractions. A flying seat cushion can cause a fatal injury .The apparently harmless glove-compartment door has been known to unlatch under impact and guillotine a child. Roof-supporting structure had deteriorated to a point where it provides scarcely more protection to the occupants, in common rollover accidents, than an open convertible.
