It's not just voters South Australian Opposition Leader Steven Marshall hopes will turn right at the March 17 election.
If the Liberals manage to form government, Mr Marshall has pledged a right-hand turn will be added to Adelaide's controversial east end tramline extension at a cost of $37 million.
He said the turn - at the intersection of King William St and North Terrace - should have been included in works currently underway, to take the line past the Art Gallery and to the site of the old Royal Adelaide Hospital.
The Liberal leader said failing to include the right turn was one of the government's most "cynical, stupid and ultimately costly transport decisions" and a Liberal government would "fix Labor's mess" in the first term.
"It's going to be in the budget from day one," he said.
The Labor government insisted the complexity and cost of including a right-hand-turn could not be justified and would actually make traffic flows worse.
Mr Marshall last month slammed a Labor promise to extend the tram network through to Kent Town and Norwood, the heartland of his Liberal electorate.
The following day, he said he would consider another Labor plan to extend the tramline along O'Connell St into North Adelaide.
Premier Jay Weatherill said on Thursday the opposition leader was "utterly confused" and took aim at the Liberals' $37 million right-turn pledge.
"It doesn't take you anywhere," he said.
"It doesn't take you any further than our vision, which is to rebuild our tram network out to North Adelaide."
Mr Weatherill made the comments during a visit to the Tonsley Innovation District to welcome a US-based company that will build cancer-fighting proton therapy machines in Adelaide.
Work on ProTom's centre of excellence will begin later this year and is set for completion in 2019.
The base will create 100 ongoing jobs, as well as 65 temporary positions during construction.
Chief executive Stephen Spotts said South Australia was chosen for the quality of its workforce.
"Engineers and tradespeople in knowledge-intensive sectors like aerospace, defence and automotive are what we're looking for, and we're thrilled by the level of talent in South Australia," he told reporters.
On International Women's Day, the premier also announced South Australians would be entitled to 10 days of paid family violence leave each year under a re-elected Labor government.
Mr Weatherill would head up a new domestic violence portfolio and said the leave would become a minimum employment standard.
