The problems described there are real but not unique to a Volt - modernistic vehicles with a low front fascia often encounter clearance problems, getting up on the dolly, ratcheting the straps down, attaching safety chains, etc. Front drives may also have nearby components that quickly wear a cut in the strap if not carefully routed over & around the wheel. I've had similar difficulties with a Buick Verano and read about them with BMW M3. There are a zillion vehicle models and the dolly makers have to compromise to address as many as possible. In the article cited above, it appears Demco went the extra mile to help the Volt owner solve his problem.
Many newer vehicles no longer use locking steer columns - they have electronic anti-theft instead. All those vehicles require the steering wheel to be tied down in some manner
if towed on a dolly that has
swiveling wheel tables. Most modern tow dollies have swivel wheel tables, but I believe the
Acme EZ Tow does not. Often the driver seat belt can be wrapped around the steering wheel to do that, but there are alternative methods as well. Demco makes a steering wheel strap - see https://www.rvautoparts.com/5975-Demco-RV-Steering-Wheel-Lock-For-Use-On-Towed-Vehicles-That-Do_p_10616.html
You might contact Demco about their dolly models and use with the Volt.
