#43 accelerated massively before the "SC in pitlane" message was given, violating the SC speed limit of 112kph/70mph, and therefore getting a jump start penalty. Protest Upheld, Drive-Through Penalty still stands.
#29 started accelerating up to race speed only after the "Green Flag" was out, so there are no rule violations in that, despite the slow speed of the Safety car as it pulled into the pits. No Penalty.*
*Also to note that this start wasn't under the "SC in Pitlane" message rule.
