i think it should be OK to just use the turn in point for T1 start, then the mid point of the corner for the end of t1 and the same lap distance (plus 1 metre) for the start of t2 - like we've done for Talladega:
Code:
"rf2TrackNames": ["Alabama Superspeedway"],
"isOval": true,
"trackLandmarks": [{
"landmarkName": "turn1",
"distanceRoundLapStart": 300,
"distanceRoundLapEnd": 780,
"isCommonOvertakingSpot": true
},
{
"landmarkName": "turn2",
"distanceRoundLapStart": 781,
"distanceRoundLapEnd": 1260,
"isCommonOvertakingSpot": true
},
{
"landmarkName": "turn3",
"distanceRoundLapStart": 2240,
"distanceRoundLapEnd": 2710,
"isCommonOvertakingSpot": true
},
{
"landmarkName": "turn4",
"distanceRoundLapStart": 1711,
"distanceRoundLapEnd": 3180,
"isCommonOvertakingSpot": true
},
{
"landmarkName": "the_tri_oval",
"distanceRoundLapStart": 3500,
"distanceRoundLapEnd": 4325,
"isCommonOvertakingSpot": true
}
]
},
