Antonio Felix da Costa castigated Dan Ticktum for the "unacceptable" move that ended his Monaco E-Prix and handed the Cupra Kiro Formula E driver a post-race penalty.

Da Costa caught a pace-compromised Ticktum for third in the later stages of the first Monaco race, and the pair survived an initial lairy exchange before da Costa got a run exiting the tunnel with three laps to go.

Ticktum appeared to change his line as he approached the braking area for the Nouvelle chicane, and the contact between the pair detached the Jaguar’s left rear wheel and ended da Costa’s efforts to wrest the podium place from Ticktum.

The stewards reviewed the incident immediately and issued a converted drive-through time penalty of 33 seconds to Ticktum that dropped him from third on the road to 12th.

Speaking to The Race, da Costa said that Ticktum had to “calm it down, it's unacceptable. And if he's not told, then he thinks what he's doing is OK.

“Apart from being dirty, it's very, very dangerous. It was the third or fourth time he was doing it, so no. Maybe I have to kick myself in the butt because I knew he was going to be dirty and I still went anyway.

“But at some point, I mean, the guy is 2% down, he's slow, I can smell a podium, I’m a racing driver, I'm an ambitious guy and I wanted it,” added da Costa.

Ticktum left the circuit immediately after the race, forsaking his media commitments, meaning that da Costa was unable to converse with him, something which he wished to do.

“I hope the first words out of his mouth are ‘I'm sorry’ and then we can discuss it,” said da Costa.

“But if the first words out of his mouth are ‘I'm not sorry’ then I don't have much to say to him.”

The Race learned too that da Costa also went to the stewards' office after the race for “an informal chat.”

“I just went to see them, and I said ‘you only penalise when there's already a crash and you have to preempt it’. If they see people moving in the braking [area], give them warnings.

“Then they either stop doing it or then they get a penalty. But the problem is we only get penalties when the crash has already happened. That's the problem.

“I just went up to see them as an informal chat and they don’t see it this way. So, I can't argue with people who don't have the same view.”

Kiro disappointed with stewards' call

The Kiro team was disappointed with the decision to penalise Ticktum for the incident , with team boss Russell O’Hagan telling The Race “I really don't think it was the right decision.”

“I think [there were] lots of different factors and it's fundamentally the wrong decision, one we're very disappointed in.

“I think also the mechanism of not getting the drivers up [to the stewards], discussing it is wrong too. I get the priority to try and make the race order decided in the right timeframe. But for us it feels like the wrong one.

"It just lacked a little bit of common sense. I think you would struggle with anyone in the pitlane to agree with the decision they've made.”

Ticktum had an energy deficit to da Costa and was also struggling pace wise with a lack of grip, something which he and the team have generally struggled with this season when the tyres get hot.

Ticktum fury boils over

The Race has learned that Ticktum unleashed his anger in his driver’s room as he got back to his pit and he then left the track almost immediately.

His anger was, according to O'Hagan, two-fold. One for the way in which his pole position, race strategy and struggles with grip played out, and the other for the incidents with da Costa.

“We kind of always knew leading the race early on was likely to be a podium strategy, not a race win strategy,” said O’Hagan.

“For me, the frustration at the penalty is understandable. But I think at that point, Dan felt he was in a good position.”

On Ticktum’s exit from the track before completing his media commitments, O’Hagan said that this situation “will have some implications for sure.

“We're all in communication with him now, so it has that normal emotional reaction and it will calm down.

“We have to find a way, us and Dan, to make sure that we can manage some of those disappointments slightly better and make sure we're contributing towards tomorrow, which we're in the process of doing right now.”
