The technology is there. The ball is kicked with the first touch.
Please define what "level" means. When is a player "level" and when are they not?
EDIT: Semi-automatic offside technology has already been used in the Champions League and Serie A.
Yes, it can. The world cup ball had a sensor (sending data 500 times per second) which allowed for a more precise detection of when the ball was kicked compared to optical tracking.
What is "level"? How far does the attacker have to be, ahead of the defender, in order to be offside?
If they are...
Offsides should be objective - you are either onside or offside (even if it is your big toe). If we really want consistency, then the rules must be clear.
1) Install semi-automated offsides, which were used at the World Cup.
2) Bin the rest (excluding goal-line technology), until the rules are clear and the refereeing is consistent.
