ABS is very important on wet, icy and heavy snow. Because it allows to fully push the breaks without locking the tieres and you can still stear the car under breaking and reduce the chance to spin. The only disadvantage of ABS is a increased breaking distance in dry conditions.
You may mixed ABS up with ESP (DTC) on icy/heavy snow. ESP should be disabled in these conditions. Read your car's operating manual.
Why have you removed the list of absolute lap times?
The chart is pretty nice but not really usefull to compare the absolute lap times. Can you please show the absolute lap times again?
