If you read the comments on the Instructable, it seems this will not work really well as it will only inflate a bike tire to 38PSI before equalling out. Bike tires run a lot higher pressure than car tires.
While in theory this seems like it could work, most bicycle tyres run much higher pressure than car tyres so you will not get your required bicycle tyre pressure. Howeever, for the sake of an emergency and getting some air into your tyre, it’s OK.
To get higher pressure out of car’s tyres to inflate the bike to a suitable level, what if the car was in a crushing machine at the time. That would work wouldn’t it?
