Checking an increasing number

Hi, I have the following problem.

I have this float, which im increasing by checking when a certain condition is false. Then I check whether a certain treshold is met.

The increasing part works, but when the float passes the treshold, here 25, nothing happens. When I set the float manually to a number above the treshold, the function works as expected.

I'm probably missing something really stupid, any insights on this?

regards, Rob

 float car1flipped = 1;
     float car2flipped = 1;
 
 void Update () {
     
     GameObject car1 = GameObject.FindWithTag("Bottom1");
     GameObject car2 = GameObject.FindWithTag("Bottom2");
     
     if (car1 == null)
             Debug.Log("Car1 is not found");
     
     if (car2 == null)
             Debug.Log("Car2 is not found");
         
     VehicleBottom1 sc1 = car1.GetComponent<VehicleBottom1>();
     VehicleBottom2 sc2 = car2.GetComponent<VehicleBottom2>();
         
         Debug.Log (car1flipped);
         Debug.Log (car2flipped);
         
         if (sc1.touchingGround == true)
             car1flipped += (1 * Time.deltaTime);
     
         
         if (sc2.touchingGround == true)
             car1flipped += (1 * Time.deltaTime);
         
             
         
         if(car1flipped >= 25 && car2flipped >= 25)
         Application.LoadLevel ("Drawscreen");
         
 
     
     }
