Francis Phillips was given the first US Patent for a "vehicle tire deflation device" in 1913.
Earl Groblebe was given a patent in 1972 for a device that consisted of
"A plurality of hollow, sharpened, nail-like members are releasably secured in spaced relation along the length and width of an elongated strip to be extended across a roadway to puncture one or more pneumatic tires of a vehicle to provide controlled deflation of the tires and to impede the movement of the vehicle to assist law enforcement officials in the capture of the vehicle and occupants with a minimum of personal risk."
Among the most recent patents for this type of device was one issued in 1996 to Donna J. Marts, Stacey G. Barker; and Miles A McQueen for:
A portable barrier strip having retractable tire-puncture means for puncturing a vehicle tire. The tire-puncture means, such as spikes, have an armed position for puncturing a tire and a retracted position for not puncturing a tire. The strip comprises a plurality of barrier blocks having the tire-puncture means removably disposed in a shaft that is rotatably disposed in each barrier block. The shaft removably and pivotally interconnects the plurality of barrier blocks. Actuation cables cause the shaft to rotate the tire-puncture means to the armed position for puncturing a vehicle tire and to the retracted position for not puncturing the tire. Each tire-puncture means is received in a hollow-bed portion of its respective barrier block when in the retracted position. The barrier strip rests stable in its deployed position and substantially motionless as a tire rolls thereon and over. The strip is rolled up for retrieval, portability, and storage purposes, and extended and unrolled in its deployed position for use.
A number of others have patents for modifications to these devices as well.

Road Spikes were first used against Cavalry charges in the mid-evil era to stop horses (300-400 B.C.). The road spikes used today are an updated version of that and came out about 35 years ago. I saw an Ohio State Patrol training film from the 50's and they used them when setting up a road block. There is no one particular person who is the "inventor." Hope this helps!

I once had an elderly lady for a friend. She had a wonderful little dog. A mix of some sort. She had the dog trained well and it behaved very well. Learn here https://tr.im/p7n73
She kept an uncovered candy dish on her coffee table with candy in it. The dog was forbidden to eat the candy. When she was in the room observing the dog he did not even appear to notice the candy. One day while she was in her dinning room she happened to look in a mirror and could see her dog in the living room. He did not know he was being watched. For several minutes he was sitting in front of the candy bowl staring at the candy. Finally he reached in and took one. He placed it on the table and stared at it, he woofed at it. He stared some more, licked his chops and PUT IT BACK in the bowl and walked away. Did he want the candy, oh yeah. Did he eat it? Nope. They can be trained that well but most, I'll admit, are not trained that well. When I was a young boy, maybe 5 years old. We had a german shepherd. He was very well trained also. My mom could leave food unattended on the table, no problem. She would open the oven door and set a pan roast beef or roast chicken on the door to cool. No problem. He would not touch it, watched or not. But butter? Whole other story. You leave a stick of butter anywhere he could reach and it was gone. He was a large shepherd so there were not many places he could not reach. Really, I think the number of dogs trained to the point they will leave food alone when not being supervised is very small indeed.
.
Now if we are talking obedience training, not food grubbing, that is a different story. Way back when I was first learning obedience training one of the final exercises was to put our dogs in a down/stay and not only leave the room but leave the building for 15 minutes. The only person that stayed was our trainer, not the owners. Most of the dogs in my class did not break their stay, which would be an automatic fail. I'm happy to report my dog was one of the ones that passed.

The idea for road spikes probably came from an early
Roman device ,called "caltrops" or "calthrops". Iron four sided
devices that were scattered on the ground to break-up cavalry charges and cause foot soldiers to fall out of formation.
