Hoo boy, now you're bringing back some memories.  The jump in that first video happened at Atlantic Speedway in Lucasville (near Sackville) NS, and I was there that night.  

It was a half mile paved oval, and basically my favourite place to go as a kid - I'd beg my Dad every week to take me there, and occasionally he'd get tired of my bugging him and give in.  My childhood friend took to bugging his Dad as well, so we'd get to go more times that way (lol).

I recall a number of special events there, including Ken Carter's jumps, Benny the Bomb (https://www.caranddriver.com/features/a15125071/the-stuntman-who-blows-himself-up-inside-cars-feature/) blowing himself up in a Chevelle, T. Cake Cook (not sure if I got his name right - when I do a search all I get are recipes...) jumping a '67 or '68 Dodge Dart over a bunch of cars, demo derbies, etc.  Of course what I liked the best was still the stock car racing.

(edit: Todd's comment reminded me of the Hell Drivers as well - in fact I have a program somewhere in my old hoarded stuff, that I got when I saw them in '71 or '72 while they were using Datsuns.  Funny story - my Dad worked at the Datsun dealership -which had switched from Pontiacs in 1971 - when they came to town and he named the junk cars that they used for their crash stunt: "Junky Jim" - the car to be hit - and "The Wild One" - the car they were supposed to drive... when we were watching the show they couldn't get The Wild One to run, so Junky Jim ended up being the one that they drove... my Dad said "yeah, that figures"...)

Anyhow, long ago I purchased the dvd for The Mad Canadian, and a feature length documentary called The Devil At Your Heels at the NFB website, link below:

The Lincoln jump is discussed at length.  It's a good watch if you have the time.
